The performance of distributed detection systems under non-coherent integration

The performance analysis of distributed detection systems has been conducted and non-coherent integration is the common method to improve the detection performance. The detection performance of a distributed surveillance radar system under non coherent integration is studied. The cell averaging constant false alarm rate (CA-CFAR) detectors and the order statistic constant false alarm rate (OS-CFAR) detectors are employed as local detectors. Using K and of N data fusion rule, we get threshold multipliers of the distributed detectors and the detection probability of the corresponding detection system. The performance change analysis of the distributed detection system is given when some local detectors failed.
