意大利Etna火山InSAR实测的SLC数据，即两幅天线的SAR复图像，mat格式，可以用MATLAB直接读取后进行图像配准、相位滤波、解缠绕等步骤。(Etna volcano, Italy measured the SLC InSAR data, that is, two antenna SAR complex image, mat format, can be read directly after the MATLAB image registration, phase filtering, winding steps of solution.)

LFM的脉冲压缩，即匹配滤波器的产生，并给出了压缩后的仿真波形。(LFM pulse compression, that is, the selection of matched filter, and gives the simulation waveforms compressed.)

用matlab编写的周期谱分析程序及数据。(cyclic spectrum)

这是IIR数字滤波器的设计及滤波程序，IIR滤波器用matlab实现，滤波数据用C生成，主程序实现数字滤波(This is the IIR digital filter design and filtering procedures, IIR filter using matlab, using C to generate filtered data, the main program to achieve digital filtering)

Solution for some problems in Codeforces

图像域上的DFS遍历，函数返回连通域数量，范围端点以及最大值(DFS traversal on the image domain, the function returns the number of connected domains, the scope of the endpoint as well as the maximum value)

说明：  modem.qammod对象实现M-QAM调制器，本示例中M为16。其输入参数是从0到15的整数而不是4bits二进制数据。因此，在利用此对象的modulate方法之前需要对二进制数据序列x进行预处理。特别地, 先采用MATLAB中的reshape函数将x沿着矩阵的行方向重新整理成每行4bit数据，然后应用bi2de函数将4bit数据转换成相应的整数。(modem.qammod object implements M-QAM modulator M in this example is 16. Input parameter is an integer from 0 to 15 instead of 4bits binary data. Therefore, before using the method of this object needs to modulate the binary data sequence x pretreatment. In particular, the first use of MATLAB reshape function x 4bit rearranged into each row of data in the row direction of the matrix, and then apply bi2de 4bit function to convert the data into the corresponding integer.)

very fantastic idea to share

说明：  噪声调频干扰信号的matlab仿真实现，其中包含成像的提取程序(SAR jamming of noise moding frequency)
