Understanding Radar Systems is a book to convey facts and figures and also explain why things are the way they are. It is written for students and young engineers in industry@ already competent in electronic engineering or physics@ who need to understand modern radar principles@ applications and some of the jargon used. There are three parts to the book. The first three chapters form an easy (and deterministic) guide to the basics of what radar is all about@ and what it can do. Chapters 4-6 are possibly more difficult because probability is introduced@ but these chapters will be necessary for those who wish to begin calculating the performance of radar systems. The remaining chapters describe different types of modern radar@ the problems and the research areas. These applications are used to introduce some more new ideas@ so that their relevance is apparent. This book can be used in several ways: as a 'streetwise' introduction to radar; as a rough guide to calculating the performance of most types of radar; or as a handy reference when starting off on a new radar topic@ before going on to the more detailed texts in that area. The most important thing is to understand the subject and enjoy your career in radar. Authors Simon Kingsley and Shaun Quegan
