Abstract

Two constant false alarm rate (CFAR) detectors are proposed for time-diversity and multiple-target situations. The first CFAR detector considered is the generalized censored mean level detector (GCMLD), which has been shown to exhibit excellent capabilities in rejecting interfering targets in homogeneous background noise for single pulse processing. The effect of correlation on the performance of a centralized GCMLD is studied. To minimize the effect of correlation among the received pulses, a distributed GCMLD with data fusion is proposed. The individual detectors are optimized, and two intelligent fusion rules are considered
