通常假设在雷达信号处理机I、Q两路通道中存 在的噪声是服从N(0，d2)分布的，经过FFT处理再取 模之后的噪声分布为瑞利分布。-Usually the noise present in the radar signal processor I, Q two channels is assumed to obey the distribution of N (0, d2) after FFT processing and then after the modulo noise distr

本程序是关于快速傅里叶变换的程序，将txt文档中的数据载入到matlab,对数据进行傅里叶变换，并实现结果。-The program is about FFT. First, translate the txt file to the matlab,then, excuse fft processor.
