In this book, I have tried to cover the different subjects to a ?greater than superficial? level. My knowledge on the subject is derived from many excellent books on the diverse subjects and therefore, the information contained in this book is nothing original, except possibly in the manner of presenting it. Over the years, I have been fortunate to have had the time to read many different books. My tenure, as an instructor in the Faculty of Guided Missiles, at the Institute of Armament Technology, Pune (now the Defence Institute of Armament Technology) with its extensive library, enabled me to read widely and cogitate on what I had read. In particular, I owe whatever I know about Missile Kinematics to the brilliant lectures of Professor PC Rath of that institute. I also learnt about blast warheads, fragmentation warheads including Gurney?s formula and Hesh warheads from the then Wing Cdr Rathuri, who used to teach air armament. But, most of the topics xviii contained in this book will be found, discussed to a far greater depth, in many of the standard books on the different subjects. Anyone wanting to know more about Radar should study Skolnik?s or Barton?s definitive books on Radar, and if one is interested in Infrared Engineering, Hudson?s book on the subject. ?Guided Missile Control System? by Garnell is a must-read for anyone wanting to learn this aspect of the subject. There are similar wonderful books on every one of the different subjects. I have included a list of references at the end of each chapter. The material contained in a chapter is based almost entirely on material in the reference books listed. Tha articles in Wikipedia and Google on the internet are excellent sources of information and I have included some references from these sources. I have written this book mostly from memory and it is possible that I have missed out some authors and sources in the references. If so, it is unintentional and my humble apologies to those missed out.
