弱信号检测中，LFM信号经过匹配滤波器的应用(Weak signal detection of LFM signal in the application of matched filter )

polarPcolor是一个函数,旨在用极坐标表示伪彩色图,与径向网格允许数据的一个简单的演讲。它非常适合平面位置显示器(PPI)扫描雷达为例。我们的目标是提供信息的极坐标给定变量Z。(polarPcolor is a function that aims to represent a pseudocolor plot in polar coordinates, with a radial grid to allow an easy lecture of the data. It is well suited for Plan Position Indicator (PPI) scan for radar for example. The goal is to provide information about the polar coordinate of a given variable Z. )

改进的有序统计类恒虚警检测器（MOS-CFAR），适合于多目标检测(detectors based on the modified ordered statistic constant false alarm rate (MOS-CFAR) technique.)

说明：  该程序可以对遥感图像进行分类，使用的方法是BP神经网络。(The program can be used to classify remote sensing images, using the BP neural network.)

该代码采用matlab和C混合编写，是采用随机梯度的方法训练线性分类器，它可用于数据、图像等的多类分类情况。参考论文：Good Practice in Large-Scale Learning for Image Classification(This a Stochastic Gradient Descent algorithm used to train linear multiclass classifiers. It is biased towards large classification problems (many classes, many examples, high dimensional data).)

在matlab环境下的一个朴素贝叶斯分类器，大家可以参考下(Matlab environment a Naive Bayes classifier, we can refer to the following)
