matlab关于微分方程的解法，只有这么多说明了(matlab on differential equations, and only so many shows)

this code do background subtraction subtracting all frames from first frame and show the result video and input video

分析BPSK在对数长距离、对数正态阴影模型中的误码率，以及在ITU M多普勒效应下冲击响应与多径增益。程序为已提交作业，可直接运行。(In the analysis of several long-distance BPSK, lognormal shadow model error rate, as well as multi-path impulse response and gain at ITU M Doppler effect. Program has been submitted for the job can be run directly.)

STA LTA 长短视窗处理地震信号算法，绝对自己编的，有很好的效果(STA LTA length windows seismic signal processing algorithms, absolutely own, and have a good effect)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)
