说明：  三维点云曲率计算，计算网格的高斯曲率、平均曲率及主曲率(Curvature calculation of three-dimensional point cloud)

每个天线单元都由独立的移相开关控制，通过控制各天线单元发射的相位，就能合成不同相位波束。相控阵各天线单元发射的电磁波以干涉原理合成一个接近笔直的雷达主瓣，而旁瓣则是各天线单元的不均匀性而造成。(Each antenna unit is controlled by an independent phase shift switch. By controlling the phase transmitted by each antenna element, different phase beams can be synthesized. The electromagnetic wave emitted from each antenna unit of phased array generates a nearly straight radar main lobe based on the interference principle, while the sidelobe is caused by the heterogeneity of the antenna units.)

遗传算法优化PID，解决传统的PID参数采用试凑的方式的问题，从而进行自整定参数( Genetic Algorithm PID，Solve using traditional PID parameters of trial and error approach problems in order to be self-tuning parameters)

说明：  用matlab分析和处理时间序列的数据，很实用！(Analysis and processing time series data by Matlab, very useful!)
