Distributed CFAR Detection Based on Unbiased Minimum-variance Estimation Algorithm

Chaohuan Hou

Abstract

In order to improve the performance of distributed constant false alarm rate(CFAR) detection,a new type of distributed CFAR scheme which takes UMVE-CFAR detector as local detectors is studied in this paper.The objective function and optimization equation of the distributed UMVE-CFAR are derived.By comparison with other classical distributed schemes,result shows that the detection performance of the distributed UMVE-CFAR is better than that of the distributed OS-CFAR in homogenous environments and multiple target situations,and worse than that of the distributed OS-CFAR against clutter edge background.
