扩展卡尔曼滤波和unsented卡尔曼滤MATLAB工具箱，很实用(Unsented extended Kalman filtering and Kalman filter MATLAB toolbox, very practical)

pwm波形输出，用来产生20ms周期的pwm波，用来驱动舵机。(the output of pwm, it is helpful to the user.)

应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 (DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.)

this file is to solve the problem of the tridiagonal and banded systems

说明：  维纳滤波后全局阈值，将图像二值化，计算油污面积(Wiener filter after the global threshold, binary image calculated oil area)

把电源系统表示成线性传递函数或非线性控制模型，以此建立一种符号仿真模型(The power system transfer function expressed as a linear or nonlinear control model, in order to establish a symbolic simulation model)

matlab编写的视频关键帧提取程序，可自动从视频中提取帧，提取第几帧可在程序中自行设定，另附有批量处理视频的主函数。(matlab prepared video key frame extraction procedures can be automatically extracted from video frames to extract the first few frames can be set in the program, batch processing video attached with the main function.)

研究压缩感知理论在脉冲雷达中的具体应用问题，同时对目标距离进行估计。(Research on the application of compressed sensing theory on pulse radar, and estimate the target distance.)

该段程序描述了如何去估计多普勒频率变化率。参考文献为Morelli的《Doppler-rate estimation for digital burst transmission》( This section describes how to program the estimated Doppler frequency rate of change. References to Morelli s "Doppler-rate estimation for digital burst transmission")

说明：  随机共振相似度的Matlab计算程序，计算看出输入-输出的相似度S随着噪音的标准差的增大而不断得到改善，直到增大至一饱和值为止。(Stochastic resonance Matlab similarity calculation process, the calculation to see input- output of the similarity S as the standard deviation of the noise increases continue to improve until the saturation value increased to 1 so far.)
