摘要
针对在圆锥扫描跟踪系统中,接收机解调出的方位和俯仰误差电压存在耦合,耦合大时,既不利于天线跟踪,也容易引起结构件的磨损,降低设备使用寿命,因此构建并提出一种通过移相技术降低交叉耦合的方法。同时对圆锥扫描原理以及实现的方法进行了简要介绍,给出了圆锥扫描以及基准的时序图,最后给出了在单片机定时器里实现这种算法的程序。
IN conical scan tracing system, there are some cross coupling of error voltage between azimuth and elevation from receiver. The function of tracing is not good when cross coupling is large. The same time antenna will be damaged quickly. So a method of reducing cross coupling based on moving phase is proposed and builds. The principle and method of conical scan is introduced, and graph of time about conical scan and reference is presented. Finally it formulates principle and method of moving phase through delaying algorithm in single chip.
