卡尔曼滤波方法解决雷达数据融合问题，本程序针对同步融合。还附有红外数据融合(Asynchronism_Radar.Asynchronism_IR.)

首先用matlab实现了识别算法的仿真，因为只是对特定的数字组合的识别，所以非常的简单，放弃采用比较复杂的识别算法，采用最普通的像素比较的识别算法。(First, to achieve the recognition algorithm using matlab simulation, because the only identification of a specific combination of numbers, it is very simple, give up the use of more complex recognition algorithms compare the most common pixel identification algorithm.)

这是一个包含PCA降维的matlab程序加上用svm分类的一个程序。(This is a PCA dimensionality reduction plus matlab program contains a program with svm classification.)

time, the function returns the order Jump to respond to the first (positive) wave peak b1, step response of the second (positive) wave peak b2, step response overshoot sigma, step response of the attenuation ratio of n, the step response of the attenuation rate pusi step response of the decay vibration cycle T, the step response of

主要是对图像实现DFT,DCT变换，利用二维小波分析对图像作二层小波分解，显示条状图，十字图及频谱等(Realize the image is mainly DFT, DCT transform, the use of two-dimensional wavelet analysis of images for the second floor of wavelet decomposition, indicating strip maps, charts and cross spectrum)

介绍matlab编程的基本知识，对于初学者来说很有用(matlab programming course )

系统学习MATLAB，讲了MATLAB内容，并附有各章例子程序(System to learn MATLAB, the MATLAB stresses the contents of each chapter with examples of procedures)

说明：  一些基本的matlab入门书籍，对于初学者比较有用……(some basic Introduction books to matlab , may be useful for beginners ... ...)

导入RENIX文件，通过卫星导航电文计算卫星的位置，并与精密星历做对比。(RENIX import files via satellite navigation data to calculate the position of the satellite, and with precise ephemeris do comparison.)
