本程序已被本人整理到WORD文档中，编程语言为MATLAB，程序中首先利用非递归法产生滤波器系数，生成相关高斯杂波，直接对杂波信号作FFT变换，结果取模平方后除以长度N,即可得到杂波的功率谱，设计参数皆在文档中表明。此程序已经验证是正确可执行的，并能生成图形，值得下载！( This program has been organized into WORD document I, the programming language MATLAB, the program produced the first method using non-recursive filter coefficients to generate the relevant Gaussian clutter, clutter signals directly to FFT transform, the result after the square modulus divided by the length of the N, can be obtained the power spectrum of clutter, design parameters are indicated in the document. This procedure has been verified is correct executable, and can generate the graph, it is worth to download!)
