摘要: 一、引言 在中等脉冲重复频率(PRF)工作时,MTI-FFT-CFAR是PD或MTD雷达信号处理器的一种典型结构。Lawrence和Moore对MTD雷达在地杂波和气象杂波背景中的检测性能的计算中,假设了邻近距离单元中的杂波样本是独立同分布的(iid)。而在MTI-FFT-频域单元平均CFAR处理器中,频域单元的杂波样本明显偏离iid假设。门

Abstract: This paper introduces the typical calculation results of the detection performance for MTI-FFT-frequency cellaveraging CFAR processing in medium PRF airborne PD radar. Under different conditions of input clutter power spectra, the effect of MTI caticelers and weighting forms on the detection performance of the processors are quantified and compared.
