在雷达成像中所用到的多普勒质心估计，用idl语言编写(In radar imaging is used in the Doppler centroid is estimated using idl languages)

说明：  介绍了MATLAB载图像处理方面的应用，并有实例介绍(Introduced the MATLAB contains image processing applications, and has examples of introduced)

一个按照时间抽取的基2快速傅里叶变换（基2FFT-DIT）。输入倒位序，输出自然顺序。(A time taken by the base 2 fast Fourier transform (base 2FFT-DIT). Enter the inversion sequence, the output of natural order.)

在输入输出信号中加入高斯白噪声。这是在很多工程领域必须加入的。此文件是matlab中信号加入高斯白噪声的文件(In the input and output signals in white Gaussian noise. This is in many engineering fields must be added. This file is in matlab adding Gaussian white noise signal file)
