本文论述雷达杂波的计算机模拟方法。用具有高斯频谱的高斯随机过程作为雷达杂波模型。采用查表法快速产生互相正交的两组独立高斯随机数列,通过低阶递归型高斯数字滤波器产生两组互相正交的模拟雷达杂波的随机数列,对它们进行了统计检验、谱分析和相关分析。这些随机数列的产生速度快、精度好,用它们作为雷达杂波环境对雷达动目标检测系统进行了计算机模拟试验,结果很好。
This article discusses the computer simulation of radar clutter. Gaussian random process with Gaussian spectrum as a radar clutter model. Two pairs of independent Gaussian random numbers that are orthogonal to each other are generated quickly by using the look-up table method. Two sets of random numbers of the simulated radar clutter orthogonal to each other are generated by the low-order recursive gaussian digital filter, and the statistical tests are performed on them. And related analysis. These random sequences are fast and accurate, and they are used as radar clutter to simulate radar moving target detection system with good results.
