说明：  合成孔径雷达( SAR) 是一种高分辨率成像雷达，可以在能见度极低的气象条件下得到类似光学照相的高分辨雷达图像。 BP算法基于时域处理回波信号，利用脉冲压缩技术实现距离向匹配滤波，方位向分辨率通过沿回波曲线进行相干叠加实现。(Synthetic aperture radar (SAR) is a kind of high-resolution imaging radar, which can obtain high-resolution radar images similar to optical photography under extremely low visibility weather conditions. BP algorithm is based on time-domain processing of echo signal, using pulse compression technology to achieve range matched filtering, azimuth resolution is achieved by coherent superposition along the echo curve.)

说明：  多元多项式拟合，将两个及两个以上的自变量与因变量你合成一个多项式方程(Multivariate Polynomial Fitting from LioTuoms)

双反星形可控整流电路simulink仿真模型，一次侧为三角形联结，二次侧为双反星形联结。(Dual anti-star controllable rectifier circuit simulink simulation model, the primary side is a triangular connection, the secondary side is a double anti-star connection.)

VB强制修改窗口标题文字源码，把程序窗口标题栏中的文字修改为指定文字，将原标题文字修改为自定义标题文字。写着玩的，不知有没有喜欢哦。

基于经验模态分解法（EMD）的Hilbert-Huang变换（HHT）的MATLAB程序。 可将非平稳信号转换为平稳信号，通过将IMF分量累加重构得到平稳信号 。 主程序为HHT.m，需要用到hhspectrum.m函数、instfreq.m函数（在压缩包内）和已安装的EMD工具箱中emd函数。(The empirical mode decomposition (EMD) method based on Hilbert-Huang transform (HHT) of the MATLAB program. The non-stationary signals can be converted into stationary signals, and the stationary signals can be obtained by accumulating and reconstructing the IMF components. The main program is HHT.m, which requires the hhspectrum.m function, the instfreq.m function (in the compressed packet) and the EMD function in the installed EMD toolbox.)
