Distributed Adaptive CMLWCA CFAR Detection Method

To find a solution to decision of detection in distributed multi-sensor systems that every sensor has its own SNR(signal-noise-ratio),a novel distributed CFAR detector,named CMLWCA(censored mean level weighted(cell-averaging),) is proposed based on LRT(likelihood ratio test).In the scheme,the weights are decided by the SNR of each sensor,therefore the detector can hold CFAR properties in spite of different SNR that sensors may have.In the case that target fluctuating is Swerling II,closed-forms of probability of detection and probability of false alarm are derived.The numerical analysis results of the CMLWCA detector show its good detection performance.
