雷达目标跟踪中的逻辑法航迹起始程序，其中包含两个文件：simutrack.m和main.m。simutrack.m是目标轨迹仿真；main.m是主文件(The logic of the radar target tracking in track initiation procedure law, which contains two files: simutrack.m and main.m. simutrack.m is the target trajectory simulation main.m is the main file)

描述了泊松方程的离散化过程和求解过程。对初学者特别有帮助！(Discrete Poisson equation describes the process and the solution process. Especially helpful for beginners!)

关于最优化理论中DFP算法的matlab实现的简单方法。(On optimization theory DFP algorithm matlab realize the easy way.)

对接收到得信号进行分离是信号处理过程中经常用到的，然而在完全不知道接受信号先验知识的情况下进行分离就是所谓的盲源分离，此程序就是重多盲源分离算法中比较重要的一种变步长自适应盲源分离算法——EASI(Butt had been received too signal separation is the signal processing is often used, but do not know to accept in full prior knowledge of the signal to separate the case of the so-called blind source separation, this procedure is more emphasis on blind source separation algorithm to compare important type of variable step-size adaptive algorithm for blind source separation- EASI)

对于具体实验时，通常不是先给出函数的解析式，再进行实验，而是通过实验的观察和测量给出离散的一些点，再来求出具体的函数解析式。又因为测量误差的存在，实际真实的解析式曲线并不一定通过测量给出的所有点。最小二乘法是求解这一问题的很好的方法，本实验运用这一方法实现对给定数据的拟合。(For specific experiments, usually not first given function analytic formula, and then experiment but given by the experimental observation and measurement of a number of discrete points, and come back to find the specific function analytic formula. And because the presence of measurement error, the actual real analytic curve does not necessarily pass through all points of measurement given. The least squares method is a good way of solving this problem, the experimental use of this method of fitting the given data.)
