alpha-β滤波器是针对匀速运动目标模型的一种常增益滤波器，本代码给出了在目标机动指标已知、未知和自适应滤波三种情况下的仿真代码(alpha-β filter is a moving target model for a uniform constant gain filter, the code is given in the target mobile targets known, unknown and adaptive filtering three cases of simulation code)

用于MATLAB作图中，多张图的合并（里面的文件路径需要根据需要更改）(For the MATLAB plot, the multiple number of pictures merger (inside the file path needs to be changed as needed))

可以读入.mav格式的音频文件，同时可以仿真出此音频文件的时域及频域的波形图，加入噪声后，可以仿真出加噪后的音频时域及频域波形，并保存新的音频文件。(Mav format audio files that can be read into simulation time domain and frequency domain waveform diagram of audio file, you can add noise simulation time domain and frequency domain waveform plus noise audio, and save the new audio files.)

极化SAR定标算法，采用最新的Withworth算法(Polarimetric SAR calibration algorithm)

这个是关于AM调制的MATLAB仿真程序，对初学MATLAB调制的来说很有用，其中含有仿真图。(This is the AM modulation MATLAB simulation program, very useful for the beginner MATLAB modulation, which contains the simulation Fig.)

后处理程序，主要是绘制单向拉伸杆中沿横截面的应力分布图(failed to translate)

二级倒立摆的matlab仿真程序，希望大家给点意见，哈哈，，，，，，(Double inverted pendulum)

说明：  这是一个关于粒子滤波的源程序，能帮初学者学习该滤波算法(This is a source on the particle filter, the filter algorithm can help beginners to learn)
