Abstract:

A new sort of constant false alarm rate (CFAR) detectors based on censored mean (CM) and cell average (CA) is proposed in this paper.They use the logic operation (the mean value,the greatest value or the smallest value) of CM and CA local estimations as a noise power estimation.Their detection performance is analyzed in a homogeneous background and in multiple interfering targets situations.The results show that the detection performance of the mean value of CM and CA detector is better.

Key words: censored mean;cell average;CFAR
