Book Review: Radar Systems Analysis by David K Barton

Radar Systems Analysis is a comprehensive and cohesive introduction to radar systems design and performance estimation. It offers professionals the knowledge they need to understand, analyze, evaluate, or design radar systems. The book presents accurate detection range equations for realistically estimating radar performance in a variety of practical situations. As radar systems evolve, designers, engineers, and analysts can turn to this book again and again to keep up with the latest advances in radar technology.

This book offers radar engineers all the fundamental and advanced information they need in day-to-day work. Readers will find several lucid chapters on various aspects of radar, such as theory of target detection, theory of radar measurement, description of radar targets, theory of search radar and its signal synthesis and analysis, error analysis, processing of radar data and tracking systems.

The book is divided into seventeen chapters starting with the theory of target detection where the radar echoes and noises are dealt with along with the integration of pulses. Chapter 2, 3 and 4 deals with the radar measurement of range, angle and velocity using the classical radar equation description, and description on RCS and complex targets. Chapter 5, 6, 7 and 8 is dedicated to the search radar and its target detection and measurement, MTI techniques, and synthesis and analysis. Chapter 9 to 14 deals extensively with the track radars which include angle measurement and tracking and its error analysis, range tracking systems, Doppler tracking systems, tracking radar data processing and its acquisition. There are discussions on the survey of propagation effects and multistation radar networks.

This book details practical procedures for search and track radar system testing and evaluation of radar range in difficult environments of combined noise, jamming, and clutter. However, an important topic like radar testing and evaluation gets one lonely chapter with somewhat cursory coverage. The book is substantiated with the adequate references and bibliography along with mathematical approximations for radar beam shape, spectra and waveforms.

Tables on transmission line and receiver input noise temperatures and table on radar range factors for system power change from 0 to 40 db have been provided for appropriate reference and use.

This excellent book summarizes the theory of radar systems and provides the radar engineer with methods and tools for estimating the performance of a wide variety of radars and for synthesizing or selecting radar designs to meet detection and tracking requirements. I recommend this book to all those interested in this fascinating field and Libraries of Technical Educational Institutions.

Oriental Wisdom & Cognitive Science

HUMOR WISDOM COGNITION THERAPY

A fascinating book on my bookshelves – ORIENTAL STORIES AS TOOLS IN PSYCHOTHERAPY : A Book Review

By

VIKRAM KARVE




An Eastern merchant owned a parrot. One day the bird knocked over an oil flask.


The merchant became very angry and hit the parrot on the back of the head.

From that time on, the parrot, who had previously appeared to be very intelligent, could not talk any more.

He lost the feathers on his head and soon became bald.

One day, as the parrot was sitting on the bookshelf in his master’s place of business, a baldheaded customer entered the shop.

The sight of the man made the parrot very excited.

Flapping his wings, he jumped around, squawked, and, to everyone’s surprise, suddenly regained his speech and asked the baldheaded man, “Did you, too, knock down an oil flask and get hit on the back of the head so that you don’t have any hair any more?”

This is a story called The Merchant and the Parrot from a delightfully interesting book in my bookcase called “Oriental Stories as Tools in Psychotherapy” by Nossrat Peseschkian. I bought this book on 12 October 1998 from the International Book Service at Deccan Gymkhana in Pune and love to delve into it from time to time.

The book features a fascinating compilation meaningful oriental Teaching Stories– the psychotherapeutic function of stories is the theme of this book. The author, a physician and psychotherapist, emphasizes the fact that long before the development of modern psychotherapy, stories served as instruments of folk psychotherapy and highlights how stories are effective transmitters of messages. He avers that stories have a lot in common with medication and, like medicines, used at the right time in the right form stories can lead to changes in attitude and behavior, but, given in the wrong dosage, told in an insincere and moralizing way, the application can be dangerous.

You can study, scrutinize and critically analyze this book if you are a serious reader and want to go deep into the subject; or like me, you can enjoy and be illuminated by the lovely teaching stories in the book.


I have read somewhere that Teaching Stories have a special quality – if read in a certain kind of way they enlighten you.

Remember, Dear Reader, that there are three ways to read teaching stories:-

• Read the story once. Then move on to another. This manner of reading will give you entertainment – maybe produce a laugh; like jokes.

• Read the story twice. Reflect on it. Apply it to your life. You will feel enriched.

• Read the story again, after you have reflected on it. Carry the story around in your mind all day and allow its fragrance, its melody to haunt you. Create a silence within you and let the story reveal to you its inner depth and meaning. Let it speak to your heart, not to your brain. This will give you a feel for the mystical and you will develop the art of tasting and feeling the inner meaning of such stories to the point that they transform you.

Let me tell you that a good teaching story has several levels of meaning and interpretation and offers us opportunities to think in new ways.


At first you may just have a good laugh, but as you think and reflect, the significance becomes more and more profound.

Each story veils its knowledge and as you ruminate, the walls of its outer meanings crumble away and the beauty of the previously invisible inner wisdom is revealed, and you begin to identify yourself in the story, and to acknowledge that you too could be as foolish or as lacking in discernment as the characters in these classic tales.

If you read the teaching stories narrated in this book in this way you will most certainly feel the therapeutic effect.

Here is a story called “Fifty Years of Politeness”:

An elderly couple celebrated their golden anniversary…while eating breakfast together, the woman thought, “for fifty years I’ve always been considerate of my husband and have always given him the crusty top of the bread roll. Today I want to finally enjoy this delicacy for myself.”


She spread the top part with butter and gave the other part to her husband.

Contrary to her expectations, he was very pleased, kissed her hand, and said, “My darling, you’ve just given me the greatest joy of the day. For over fifty years I haven’t eaten the bottom part of the bread roll, which is the part I like best. I always thought you should have it because you like it so much.”

I love and cherish this book which has enhanced me in all aspects of my life and browse through the stories quite often; and as I reflect and interpret I feel refreshed, enlightened and wiser.


Whether it is your work, you marriage, you relationships, children, or any situation or facet of your life, there is sure to be an apt story in this book for you which will put you on the path of self-discovery.

I’ll conclude with a quote from this exquisite and unique book:


Occasionally we can’t avoid science, math and erudite discussions which aid development of human consciousness. But occasionally we also need poetry, chess, and stories, so our spirit can find joy and refreshment.

I truly liked this delightfully illuminating book - I am sure you will like it too!

The Importance of Understanding

UNDERSTANDING LIFE - The Art of Living

By

VIKRAM KARVE


[ Book Review of THE IMPORTANCE OF UNDERSTANDING by LIN YUTANG ]



Whenever I want to unwind and relax, I pick out one of my favorite books from my bookcase, settle down in my easy-chair, put my feet up, and open the book to any random page, or thumb through the pages, and dip into whatever arrests my attention, and as I begin reading I experience a soothing feeling and a calm tranquil sensation of absolute and perfect relaxation. From time to time, I let myself drift off into sweet slumber, and when I come around I begin my relaxed reading again. So the cycle continues till my mind recaptures the harmony it has lost during the hustle and bustle of daily life and my inner self feels soothingly nourished.

The book is called THE IMPORTANCE OF UNDERSTANDING and is compiled by Lin Yutang, who is more famous for his magnum opus THE IMPORTANCE OF LIVING, the classic seminal philosophical masterpiece on The Art of Living. I have written about this classic book in my blog and request you to please read my book review in the preceding blog post. Now about The Importance of Understanding.

I’ve got a hardcover copy of the book, published by Heinemann London in 1961, which I obtained, by a stroke of luck, from a raddiwala a few years ago. The book comprises translations from the Chinese. There are essays, reflections, poems, ancient wit and wisdom, literature, writings on The Art of Living, Enjoyment of Life and Zen, parables, epigrams and proverbs. The writings focus on the simple joys of living and distinction between the practical and the poetic vision of life.

There is wit and subtle humor throughout the book. As a sample of the fantastic wit and wisdom encapsulated in this book, here is a story titled “Prohibition” from the chapter on Ancient Wit and Wisdom.

In the time of the ruler of Shu, Shienchu (third century AD) there was prohibition on wine on account of a drought…There were people who were arrested for having vats and distillery apparatus in their houses, punishable in the same terms as those actually caught making illegal liquor. Chien Yung was driving in the country with the ruler when they saw a young man strolling leisurely.
“Have that man arrested,’ cried Chien Yung.
“What has he done?” asked the ruler in puzzlement.
“He is going to commit adultery.”
“How do you know?”
“He has the organs of adultery, just as those people have their vats.”
The ruler broke out into a loud laugh and ordered that the people arrested for mere possession of vats released.

The meat of the book is the section on “Home and Daily Living” which encompasses a wide range of facets of the art of living and enjoyment of daily life.

I’ll end with an epigram of Yuan Chunglang: Beware of the man who has no hobbies. If he is not sincere in loving what he loves, he is also probably not sincere in hating what he professes to hate.

Dear Reader, first read The Importance of Living and then read The Importance of Understanding. And I’m sure you will see your life from a different perspective.


If you liked this philosophy of life do read my book:

An Inspiring Book on Leadership Styles

INSPIRING LEADERSHIP

19 STARS: A STUDY IN MILITARY LEADERSHIP

By

EDGAR F. PURYEAR Jr.

[Book Review by Vikram Karve]


It was indeed a pleasant surprise to chance upon this engrossing treatise buried in the books that adorn the shelves of my bookcase, last evening.


I had first read this book long long back, maybe fifteen years ago. I read it again. I enjoyed the book thoroughly and found it inspiring, educative, enjoyable and stimulating, and decided to tell you, dear reader, about it.

“19 Stars” is a comparative study of the contrasting styles of leadership by four of the most outstanding American generals of World War II.

The book attempts to capture those elusive qualities that have made great leaders of Generals Marshall, MacArthur, Eisenhower and Patton. The title of the book symbolizes the total number of ‘stars’ these four Generals wore on their collars.

The book starts with a lucid description of their early years as Cadets and traces their diverse backgrounds.

It is revealed that whereas MacArthur and Patton belonged to families with rich military heritage, Eisenhower grew up with no knowledge of, or any inclination towards, a military career. He could not afford to go to college, qualified for entrance to Naval Academy, Annapolis, but was overage, so opted for West Point, which had a higher entering age.

Marshall just decided to follow his elder brother into the Army.


MacArthur’s career as a cadet was brilliant.

Patton distinguished himself in the qualities of a soldier and athletic skills but faced difficulty in academics.

Eisenhower has been depicted as indifferent, carefree and careless.
An absorbing narrative encompassing World Wars I and II and the interregnum is the highlight of the book. It is a thoroughly researched analysis interspersed with a large number of anecdotes and reminiscences.


The author avoids platitudes and presents his analysis with remarkable candour.
Whether it be the ‘flamboyant’ Patton, ‘imperious’ MacArthur, ‘genial’ Eisenhower or ‘austere’ Marshall, a pattern of common leadership qualities emerges despite their contrasting temperaments.


It is revealing that these intrepid men were groomed under the tutelage of various patrons who not only furthered their careers but also bailed them out of professional crises on a number of occasions.

The numerous first person reminiscences of eminent personalities, lucidly illustrate the universal respect and honest relationships, totally devoid of sycophancy that they developed and loyally sustained.

Hallmarks of leadership like Decisiveness, sometimes based on a “Sixth Sense”, Outspokenness, and an uncanny knack of spotting the right man for the right job are highlighted in various episodes, as also their inner strength and courageous attitude towards reversals and adversities, over which they invariably triumphed.

The author has succeeded in organizing and presenting his analysis in an extremely streamlined and readable manner.

This is a very inspiring, educative and enjoyable book which is do delightfully written that once you start reading it, it’s unputdownable.

ART and SCIENCE of LEADERSHIP

ART OF LEADERSHIP

Book Review: A Soldier’s Story by Omar N. Bradley

[Reviewed by Vikram Waman Karve]


I love reading autobiographies, as there is nothing more inspiring and authentic than learning about the life, times, thoughts and views of a great person in his own words.

It’s a lazy hot Sunday afternoon. I browse through my bookshelves and pick out A Soldier’s Story by General Omar Nelson Bradley, one of my favourite autobiographies, and certainly my all time favourite military autobiography. Come Dear Reader, sit with me for a while, and let’s leaf through and peruse this fascinating book.

General Bradley (1893-1981) known for his calm and resolute leadership and affectionately called the “Soldier’s General” commanded the largest American combat force in history and rose to be the first Chairman of the US Joint Chiefs of Staff.

This is a story, not of my life, but of a campaign…I have sought... to tell a story of how generals live and work at their chosen profession the author says at the beginning of his memoirs which focus on his participation in World War II.

Candidly written with remarkable humility in beautiful expressive language it is a wonderful memoir embellished with interesting episodes and lucid characterizations of many renowned military personalities.

In the preface General Bradley says: “In this book I have tried to achieve one purpose: To explain how war is waged on the field from the field command post… To tell a story of how and why we chose to do what we did, no one can ignore the personalities and characteristics of those individuals engaged in making decisions…..Where there are people, there is pride and ambition, prejudice and conflict. In generals, as in all other men, capabilities cannot always obscure weaknesses, nor can talents hide faults…I could not conscientiously expurgate this book to make it more palatable…if this story is to be told, it must be told honestly and candidly…”

The author writes in a wonderfully readable storytelling style and starts his riveting narrative on September 2, 1943, driving to Messina along the north coast of Sicily when, suddenly, General Eisenhower summoned him to tell him that he had been selected to command the American Army in the biggest invasion of the war – the liberation of Europe from the Germans. He then goes back in time and starts his story with vignettes from his early formative days of soldiering.

General Bradley vividly describes how, from General Marshall, he learnt the rudiments of effective command which he himself applied throughout the war: “When an officer performed as I expected him to, I gave him a free hand. When he hesitated, I tried to help him. And when he failed, I relieved him” - isn’t this leadership lesson valid even on today’s IT driven world where delegation seems to be taking a back- seat and excessive monitoring, interference and intervention seem to be on the rise.

Rather than encourage yes-men, ego-massage, sycophancy and groupthink, General Marshal sought contrary opinions: “When you carry a paper in here, I want you to give me every reason you can think of why I should not approve it. If, in spite of your objections, my decision is to still go ahead, then I’ll know I’m right”.

When it was suggested to General Marshall that a corps commander who had an arthritic disability in the knee be sent home rather than be given command of a corps in the field in war, he opined: “I would rather have a man with arthritis in the knee than one with arthritis in the head. Keep him there”.

“For the first time in 32 years as a soldier, I was off to a war” he writes on his assignment overseas in February 1943 to act as Eisenhower’s “eyes and ears” among American troops on the Tunisian front in North Africa.

He vividly describes the chaos after the American defeat at Kasserine, the arrival of Patton on the scene who growled “I’m not going to have any goddam spies running around in my headquarters” and appointed Bradley as his deputy, a defining moment which was the first step of Bradley’s illustrious combat career.

This is easily the best book on Patton’s stellar role in World War II, complementing General Patton’s Memoirs War As I Knew It and Patton: Ordeal and Triumph by Ladislas Farago. Though his admiration for Patton is evident, General Bradley writes about his long association with Patton with fairness and honesty and reveals unique and remarkable facets of Patton’s leadership style and character.

Sample this – Precisely at 7 Patton boomed in to breakfast. His vigour was always infectious, his wit barbed, his conversation a mixture of obscenity and good humour. He was at once stimulating and overbearing. George was a magnificent soldier. (Can there be a better description of General Patton?)

Bradley vividly describes how Patton transformed the slovenly and demoralized II Corps into a fighting fit formation. “The news of Patton’s coming fell like a bombshell on Djebel Kouif. With sirens shrieking Patton’s arrival, a procession of armoured scout cars and half-tracks wheeled into the dingy square opposite the schoolhouse headquarters of II Corps…In the lead car Patton stood like a charioteer…scowling into the wind and his jaw strained against the web strap of a two-starred steel helmet.”

General Bradley writes superbly, as he describes how Patton stamped his personality upon his men and by his outstanding charismatic leadership rejuvenated the jaded, slovenly, worn-out, defeated and demoralized II Corps and transformed it into a vibrant, disciplined, fighting fit organization that never looked back and went on winning victory after victory in most difficult circumstances and against all odds.

There are bits of delightful humour in this book. Commenting on the ingenuity and improvisation abilities of Patton’s staff, the author writes: “…Indeed had Patton been named an Admiral in the Turkish Navy, his aides could probably dipped into their haversacks and come up with the appropriate badges of rank…” Though, at times, the author appears to be in awe of and enamoured by Patton’s larger than life charisma, he is candid, dispassionate and, at times, critical when he describes how he was bewildered by the contradictions in Patton’s character and concludes: “At times I felt that Patton, however successful he was as a corps commander, had not yet learned how to command himself.”

Their techniques of command varied with their contrasting personalities. While the soft-spoken unassuming Bradley preferred to lead by suggestion and example, the flamboyant Patton chose to drive his subordinates by bombast and threats, employing imperious mannerisms and profane expletives with startling originality; and both achieved spectacular results.

Many of us are at a loss for words when asked to qualitatively appraise our subordinates. See how easily General Bradley lucidly evaluates his division commanders, bringing out their salient qualities, in so few words with elegant simplicity and succinctness: “…To command a corps of four divisions, toughness alone is not enough. The corps commander must know his division commanders, he must thoroughly understand their problems, respect their judgment, and be tolerant of their limitations…among the division commanders in Tunisia, none excelled the unpredictable Terry Allen in the leadership of troops…but in looking out for his own division, Allen tended to belittle the role of others… Ryder had confirmed his reputation as that of a skilled tactician…his weakness, however, lay in the contentment with which he tolerated mediocrity…the profane and hot-tempered Harmon brought to the corps the rare combination of sound tactical judgment and boldness… none was better balanced nor more cooperative than Manton Eddy…though not timid, neither was he bold; Manton liked to count his steps carefully before he took them.” Aren’t the author’s understanding, observation and articulation precise and remarkable?

Throughout the book, we find honest, frank and incisive appraisals of characters in this story – superiors, peers and subordinates – most of them renowned and famous personalities. He writes with candour about the problems of command during the planning of the invasion of Europe.

From then on the story gathers speed and moves so captivatingly that one is spellbound as one reads the author fluently narrate the events of the campaign with remarkable preciseness and detail, one realizes what an engaging and compelling book this is – it’s simply unputdownable!

All important events, turning points, and personalities are vividly described with the aid of maps, charts, pictures and appendices; from D Day (the Normandy Invasion) to the surrender of the German forces. Towards the end of his memoirs General Bradley reflects “Only five years before…as a lieutenant colonel in civilian clothes, I had ridden a bus down Connecticut Avenue to my desk in old Munitions Building… I opened the mapboard and smoothed out the tabs of the 43 US divisions now under my command…stretched across a 640-mile front of the 12th Army Group...I wrote in the new date: D plus 335…outside the sun was climbing in the sky. The war in Europe had ended.”

While this autobiography is a “must read” for military men and students of military history, I am sure it will benefit management students and professionals for it is an incisive treatise on Soft Skills encompassing aspects of Leadership, Communications, and most importantly, the Art of Human Relations Management in the extremely complex and highly stressful scenario of War where achievement of success (victory) is inescapably paramount. It is a primer, a treasury of distilled wisdom, on all aspects of management, especially human resource management. One can learn many motivational and management lessons from this book.

Nothing can surpass the experience of learning history first hand from a man who lived and created it rather than a historian who merely records it.

The Art of Leadership is better learnt from studying Leaders, their lives, their writings, rather than reading management textbooks pontificating on the subject and giving how-to-do laundry lists.

The Art and Science of Management owe its genesis and evolution to the military. Modern Management theories, concepts, techniques and practices emerged from the experiences and lessons learnt during World War II [particularly in The United States of America].

It’s ironic isn’t it that the reverse is happening today?

It was the military that gave modern management principles to the civilian corporate world, and today we see military men running to civilian management institutes to “learn” management and acquire the coveted MBA which is the sine qua non and all important passport for entry into the corporate world.

I love reading stories, all kinds of stories, fiction, fantasy, parables, fables, slice of life. I like Life Stories, biographies, particularly autobiographies, as there is nothing more credible, convincing and stimulating than learning about the life, times and thoughts of a great person from his own writings. It’s called verisimilitude, I think.

A Soldier’s Story is a magnificent book. A unique masterpiece, a classic!


This autobiography is enjoyable, engrossing, illuminating and inspiring.

Dear Reader, I commend this superb book.

Do read it; I am sure you will learn a lot about the art of leadership and feel inspired by this life story.
