DETECTION PERFORMANCE OF DIGITAL POLARITY SAMPLED PHASE REVERSAL CODED PULSE COMPRESSORS
极性采样倒相编码数字脉冲压缩处理器的检测性能

The nonparametric constant false alarm rate (CFAR) property of digital polarity sampled phase reversal coded pulse compressors is described. The detection performance in Gaussian and non-Gaussian noise is determined. It is shown that the loss in signal-to-noise ratio of the processor, relative to the incoherent matched filter, decreases as the code length increases, the asymptotic loss in Gaussian noise is 1.96 dB, and the loss in Weibull noise decreases with the shape parameter of the Weibull distribution and can even become a gain.
