A CFAR algorithm based on summations processing

An Phan, Sandun Kodituwakku, Tri-Tan Van Cao

Abstract

A new radar constant false-alarm rate (CFAR) algorithm, denoted as Sum-CFAR, based on the processing of the summations of reference cells is proposed. The new algorithm employs a censoring technique similar to the traditional censored cell-averaging (CCA) CFAR. The innovation is that instead of processing each individual reference sample, the summation of at least two reference samples are processed. Performance analysis with exponentially distributed interference shows a detection improvement of up to a few dBs compared with the traditional CCA-CFAR.
