Radar Systems, Peak Detection and Tracking
- Michael Kolawole, Professor at the Monash University, Australia, also electronic engineer working in the radar and detection area.
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.View full description
