说明：  qpsk仿真程序，模块，是一个完整的好程序 不可错过阿。(keying simulation program, module, is a complete program is not to be missed A.)

处理ERS数据的SAR成像matlab代码(ERS data processing matlab code of the SAR imaging)

对于高程数据的处理，通常需要各种格式之间的转换，此程序是将usgs高程数据转为dem格式的数据。(For the treatment of elevation data, usually need to convert between various formats, this program is the USGS elevation data to DEM format data. )

调用RKF78的子过程，步长控制采用《人造卫星精密轨道确定》(RKF78 call sub-process, step-size control of the use of )

某火箭在空中沿直线做匀加速飞行，加速度为 ，发动机推力的波动一定会引起加速度波动，雷达以间隔时间不断测量该火箭距离远点的距离 ，由于雷达的测量噪声使得火箭距离测量值 中含有噪声。现在欲通过雷达对火箭距离的测量数据求得火箭的真实距离、速度和加速度。(A linear constant acceleration rocket flight in the air along the acceleration, the engine thrust fluctuation will cause the fluctuation of acceleration time interval measurement, radar to constantly the rocket from the far point of the distance, because the noise radar makes the rocket range measurements with noise. Now, the real distance, velocity and acceleration of the rocket are obtained by measuring the distance of the rocket by radar.)

模糊PID控制源程序.采样时间为1ms,在第300个采样时间时控制器输出加1.0的干扰.(Fuzzy PID control of the source code. Sampling time of 1ms, at No. 300 when the controller output sampling time add 1.0 interference.)

说明：  该程序包含低通、高通滤波功能的轮次平稳性检验法(The program includes low pass, high pass filter function in a smooth round test method)

基于Matlab-Simulink仿真的双闭环直流调速系统的设计与研究 如题,设计要求、设计公式及计算过程比较清晰,格式也是按照标准设置的,正文限于公式编辑的格式,排版不是太完美(Design and Research of Matlab-Simulink simulation of double-loop DC speed control system, such as the title, design requirements, design formulas and calculation process is relatively clear, but also in accordance with the standards set by the format, text format is limited to a formula editing, typesetting is not perfect)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)
