The book is composed of fifteen chapters. The main contents are classical detection with fixed threshold，mean-level type CFAR detectors，order-statistics type CFAR detectors，generalized order statistics CFAR detectors with automatic censoring technique，adaptive CFAR detectors，CFAR processing in Weibull and Lognormal clutter，CFAR processing in compound Gaussian clutter，nonparametric CFAR processing，clutter map CFAR processing，CFAR processing in transform domain，detection of range-spread target，distributed CFAR processing with multisensor and other CFAR methods.A brief review with suggestions and prospects is shown in the last chapter. This book is targeted for scientist and researchers engaged in radar engineering，sonar technique，electronic engineering，signal and information processing etc. It can also serve as a textbook of graduate students majoring in the above areas.
