This is a comprehensive book about modern radar techniques, describing systems and methods at the college and graduate student level. It covers radar principles, radar technology and the application of that technology. This book starts with Radar Cross Section (RCS) simulation and radar frequency synthesisers, describes a manipulation of RCS with plasma, and develops a millimetre wave frequency synthesiser for radar systems. Next, multi-pulse performance evaluation of adaptive detection of fluctuation radar targets and a C-band radar over an urban area are introduced, followed by the interpolation of the radial velocity data from coastal HF radars. At the finish, three-dimensional synthetic aperture radar (SAR) mechanisms and imaging is introduced, followed by GPU-based SAR raw data simulation for a complex three-dimensional scene. This book will be of practical use to engineers, technicians, planners, specifiers, and managers who work with radar systems and with systems containing radars and radar technology.
