这里包括synthetic aperture radar signal processing with matlab algorithms 英文书以及附带源代码，书是全英文的，作者是Mehrdad Soumekh，书中有详细的雷达信号处理方法，附带程序中的成像算法包括一维距离像、条带式、聚束式等多种模式的SAR成像。可以作为有一定SAR基础的同行的编程参考。 (The files include the book of synthetic aperture radar signal processing with matlab algorithms English books and its source code, book is in English, the author is Mehrdad Soumekh. The imaging algorithm includes a one-dimensional range profile, band type, spotlight SAR imaging a variety of modes. SAR can be used as the basis of a certain peer programming reference.)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

通过不同的时间段去选择退出时间，这样有效的控制操作。 (limited time)

CVPARTITION Create a cross-validation partition for data. An object of the CVPARTITION class defines a random partition on a set of data of a specified size. This partition can be used to define test and training sets for validating a statistical model using cross-validation.
