matlab下的m file代码——频率为3Hz的高斯白噪声信号代码(based on matlab s m file----a random signal with the frequency of 3Hz)

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

说明：  关于Matlab课件，便于大家的学习和工作，是很好滴(On the Matlab software, to facilitate everyone' s learning and work, is a good drop)

本代码实现动态物体的识别与跟踪，但注意本代码只能检测单物体且背景是静止不动的。(The code identification and tracking moving objects, but note that this code can only detect a single object and the background is stationary.)
