First, it begins with the study of the centralized CFAR detection with multiple sensors. The non-CFAR problem is analyzed; the necessity for local CFAR processing is established. The effective local CFAR processing scheme is proposed, i.e. the local test statistic. The upper limit of the optimal performance is proved for the distributed CFAR detection based on LTS. Then, the new schemes based on LTS are analyzed in condition of signal pulse, and then the analysis is expanded to the case of multiple pulses. Next, the feedback mechanism is introduced. At last, the invariant test is used to reveal the essence of CFAR processing. It explains the necessity of local CFAR processing in the distributed CFAR detection at a higher level.
