卡尔曼滤波在目标跟踪中应用仿真研究。 子函数能完成对运动目标位置的卡尔曼滤波跟踪。 主函数针对一具体假设完成跟踪，并且完成蒙特卡罗仿真。 情景假定：有一两座标雷达对一平面上运动的目标进行观测，目标在 0-600秒沿x轴作恒速直线运动，运动速度为15米/秒，目标的起始点为(-10000米，2000米)。雷达扫描周期T=2秒，x和y独立地进行观测，观测噪声的标准差均为100米。(This program described the Kalman filter algorithm according to a given scenario, simulation achieved the target tracking observation data and Kalman filter results, and the experimental results is studied using the Monte Carlo simulation. )

雷达回波信号，去除射频干扰，干扰特性为距离相干极强，stft(RF interference suppression of radar signals)

说明：  用牛顿迭代的方法，编写程序，是函数迭代的效率提高，比一般的迭代法要好很多(By Newton iteration method, the preparation procedure is to improve the efficiency function iteration, iterative method than the average much better)

现代信号处理中常用的两种变换——短时傅里叶和魏格纳变换的matlab函数程序(two usual transformtions in modern signal processing_STFT and WVD. These are matlab codes. )

双目资料，很好的学习资料，帮助很大，谢谢大家(Binocular information, good learning materials, helpful, thank you)

说明：  Matlab的Aerospace Blockset模块的介绍和应用，是mathwork公司提供的文档。(Aerospace Blockset of Matlab introduction and application module is provided mathwork documents.)

matlab入门到精通，对初学者和高手都非常有用。(Entry to the proficient in matlab, is very useful for beginners and master.)

多因子量化选股策略，包括数据导入，分组，回测分析(Multi-factor stock selection strategies to quantify, including data import, grouping, backtesting analysis)

都是MATLAB的课件,都值得仔细看看,要采用啊,不要浪费资源(are MATLAB courseware are worthy of a closer look at, to use ah and not waste resources)
