雷达系统建模与仿真的matlab程序，包括产生十种随机分布，产生swerling杂波，以及产生回波，进行快速傅立叶变换，脉压，进行MTI，以及横虚警(Radar System Modeling and Simulation of matlab procedures, including dozens of randomly generated distribution, swerling have clutter, as well as the resulting echo, fast Fourier transform, pulse pressure, the MTI, as well as cross-false alarm)

说明：  蝙蝠算法案例，蝙蝠算法是一种智能优化算法，可用于最小值问题。(Bat algorithm case, Bat algorithm is an intelligent optimization algorithm can be used for minimum problems.)

电力电子技术 课程讲解 晶闸管的介绍 过流保护 过压保护等等(Power Electronics Technology Course introduction explaining current protection thyristor overvoltage protection, etc.)

说明：  romberg求积分，用C++编程实现的 非常好用 谢谢下载(romberg I)
