实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)

this program describes the partical filter and extended kalman filter used to reduce the error to get better accuracy of the position

检测时间序列的平稳性，可以说是一种新的检测混沌的方法(Detect stationary time series, it can be said is a new method of detection of Chaos)

自己编写的一个Susan滤波算法，滤波效果很好，值得推荐(I have written a Susan filtering algorithm, the filtering effect is very good, worth recommending )

说明：  无源雷达接收机的系统仿真设计，包含频率带宽等信号仿真(System Simulation Design of passive radar receiver, including signal simulation frequency bandwidth)

说明：  这是黑龙江大学自控理论专业同学编写的二段递推最小二乘法!(This is the theory of controlled Heilongjiang University students prepared by the professional noticing recursive least squares method!)
