提供一个cell-weraging constant false alarm rate (CA-CFAR)的算法，基于信号检测的方法。-We present a method for evaluating the performance of

cell-weraging constant false alarm rate (CA-CFAR) processors

which use the anplitude of echo signals rather than their

squared amplitude Results are presented for the case of Rayleigh

clutler/mise statistics for which some sirnulatiom have been

reported recently by other authors [:I. Detection probabilities are

evaluated for the case of a Rayleigh fluctuating target embedded

in Rayleigh clutter/noise for linear-law CA-CFAR processors.

These results are observed to be practically identical to those of

square-law CA-CFAR processors for which analytical expressions

are readily available. We also verify these observations using

Monte Carlo simulations. The same conelusion is reached in the

case of a nonfluctuating target embedded in Rayleigh clutter/noise

for which only simulation results are presented here.
