✦ Synopsis

As well as being fully up-to-date, this book provides wider subject coverage than many other radar books. The inclusion of a chapter on Skywave Radar, and full consideration of HF / OTH issues makes this book especially relevant for communications engineers and the defence sector. Explains key theory and mathematics from square one, using case studies where relevant Designed so that mathematical sections can be skipped with no loss of continuity by those needing only a qualitative understanding* Theoretical content, presented alongside applications, and working examples, make the book suitable to students or others new to the subject as well as a professional reference
