本文介绍了几种相干处理器的抗杂波性能。对每一种处理器在对目标径向速度的随机分布作了假定,并且包含脉冲重复频率参差的情况下,确定了信号干扰比改善因子与目标多卜勒速度的函数关系和检测概率与信号干扰比的函数关系。所考虑的相干处理器包括用两种方法实现的6脉冲有限脉冲响应(FIR)多卜勒滤波器链,6脉冲自适应动目标显示器(MTI)和3脉冲自适应MTI。为了参考也研究了最佳相干处理器。在柱状图概述中用一个叫做“杂波因子”的品质因数描述了所有处理器的相对性能。用杂波因子可以对不同类型相干处理器的性能直接定量地进行比较。
This article describes the anti-clutter performance of several coherent processors. For each processor, the random distribution of target radial velocities is assumed and includes the pulse repetition frequency variation. The function of the signal to interference ratio improvement factor and the target Doppler velocity is determined and the relationship between the detection probability and the signal Interference ratio function. Coherent processors under consideration include a 6-pulse finite impulse response (FIR) Doppler filter chain, a 6-pulse adaptive moving-target display (MTI) and a 3-pulse adaptive MTI implemented in two ways. The best coherent processor was also studied for reference. In the histogram overview, the relative performance of all processors is described by a figure of merit called “clutter factor.” The clutter factor allows a direct and quantitative comparison of the performance of different types of coherent processors.
