说明：  雷达系统仿真，完成巴克码的调制与解调功能，完成脉压信号的参数检测功能(radar simulation)

根据输入的行星质量，初速度生成行星的运动轨迹动画。(According to the input of the planet' s mass, initial velocity of the planet' s trajectory generated animation.)

说明：  Nakagami-m分布能用来对比瑞利分布条件更苛刻的衰落信道进行建模，最适合于郊区无线多径信道上接受的数据信号，瑞利分布是它 时的特例。(Nakagami-m distribution can be used to model fading channels with more stringent Rayleigh distribution conditions. It is most suitable for data signals received on suburban wireless multipath channels. Rayleigh distribution is its special case.)
