09系分习题与解答，适合系统分析人员的学习资料和技术文档(Exercises and answers to sub-09 system is suitable for systematic analysis of the learning materials and technical documentation)

matlab最全的命令集合，学习matlab好帮手(MATLAB the most complete command set, learning matlab a good helper)

成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

该程序中包含了小波包分解和重构程序、单尺度分解、多尺度分解等，还有一些试验数据，对初学者有很大的帮助。(The program includes a wavelet packet decomposition and reconstruction program, a single scale decomposition, multiscale decomposition, there are some experimental data, for beginners is a great help.)

该文件实现了将医学图像从dicom格式转换为bmp格式，是医学图像处理中至关重要的一步。(The document will be achieved medical images from dicom format to bmp format medical image processing is a crucial step.)

本程序为应用小波变换进行信号压缩。由于本程序涉及到了小波变换的函数，因此可能涉及到一些时频分析工具箱的函数。程序中应用db3小波进行3层分解，选用全局阈值进行阈值处理，即对各高频系数使用同一个阈值，进行阈值处理。(This procedure for the application of wavelet transform for signal compression. Since this procedure involves the wavelet transform of the function, it may involve a number of time-frequency analysis function of the toolbox. Procedures for the application of layer 3 to db3 wavelet decomposition, selection of the overall threshold threshold treatment, that is, on the high-frequency coefficients using the same threshold, the threshold for treatment.)

MATLAB实现截屏的小程序,能够进行部分截取(MATLAB implementation applet screenshot)

这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

说明：  该程序实现用MATLAB实现了ART算法(The program implemented by the MATLAB implementation of the ART algorithm)
