The Performance of a Multi-Channel N:M Detector Using CFAR (Constant False-Alarm Rate) against White Noise Jamming.

Abstract

The detection performance of an N:M (N out of M) detector radiating on M independent channels and using CFAR in the individual channels is analyzed in the presence of white noise jamming with Rayleigh amplitude statistics. The zero to 10 channels equally jammed, detecting a target having Rayleigh channel-to-channel amplitude statistics and equal average powers in all channels. The design PD is 90% and the design PFA is 10 to the Minus 6th power. It is shown that under these conditions the optimum choice for N is always less than or equal to 3, with small values being most appropriate for situations with many channels being heavily jammed.
