用于图像分块，将图像分为大小一致的图像，便于图像像素位置的确定(For the image block, the image into an image of the same size, easy to determine the location of the image pixel)

MTI AND PD RADAR USE MATLAB 书中的源代码，不是最全的，但是最新的。 新买的原版书附件，第一次放在网上，其他应该地方下不到。(MTI AND PD RADAR USE MATLAB code of the book)

说明：  預失真是一種用於改善無線電發射機放大器線性度的技術。大多數電信系統中的無線電發射機放大器需要是“線性的”，因為它們必須準確地再現其輸入端存在的信號。 壓縮其輸入或具有非線性輸入/輸出關係的放大器導致輸出信號濺到相鄰的射頻上。 這會對其他無線電信道造成乾擾。(Predistortion is a technique used to improve the linearity of radio transmitter amplifiers. Radio transmitter amplifiers in most telecommunications systems are required to be "linear", in that they must accurately reproduce the signal present at their input. An amplifier that compresses its input or has a non-linear input/output relationship causes the output signal to splatter onto adjacent radio frequencies. This causes interference on other radio channels.)

信号子空间变换算法(SST)的聚焦矩阵是利用各频率点与参考频点之间信号子空间的关系导出的.(The focus matrix of signal subspace transform (SST) algorithm is derived from the relationship between the signal subspace of each frequency point and the reference frequency point.)

This Matlab code shows how to perform edge detection by Sobel method in horizontal & vertical direction and the effect of increasing and decreasing the threshold value . Besides, you can try to perform the edge detection by other method in the same ways such as Prewitt , Roberts , Canny and others.
