利用对已知样本的学习，测试，从而对未知样本进行分类！(Study using the known sample, test, and thus to classify the unknown samples!)

说明：  This document explains how to read the RADARSAT data CD provided with the book "Digital Processing of Synthetic Aperture Data" by Ian Cumming and Frank Wong, Artech House, 2005. On this web site, programs are provided in MATLAB to read the data and parameters from the CD. The structure of the programs is outlined in Figure 1. There are two main programs and one function that are used to extract

小波变换（wavelet transform，WT）是一种新的变换分析方法，它继承和发展了短时傅立叶变换局部化的思想，同时又克服了窗口大小不随频率变化等缺点，能够提供一个随频率改变的“时间-频率”窗口，是进行信号时频分析和处理的理想工具。它的主要特点是通过变换能够充分突出问题某些方面的特征，能对时间（空间）频率的局部化分析，通过伸缩平移运算对信号（函数)逐步进行多尺度细化，最终达到高频处时间细分，低频处频率细分，能自动适应时频信号分析的要求，从而可聚焦到信号的任意细节，解决了Fourier变换的困难问题，成为继Fourier变换以来在科学方法上的重大突破。(wavelet transform)
