一种基于单片机的导引头进动信号产生方法

A Method Based on SCM to Generate Precession Signal of Seeker

研究了导引头进动信号常见的产生方法,根据进动信号的特点,提出一种新的产生方法,采用数据存储队列和锁相倍频实现进动信号相位移相和频率控制,给出了方法的原理、实现电路和程序设计。对产生的进动信号测试表明,这个方法完全满足导引头跟踪的要求。方法简单、成本低廉、应用广泛。

Emulation of seeker tracking is signality,on the background of that,study the common method to generate precession signal of seeker,present a new method base on the characteristic of precession signal,realize phase shift and frequency control of precession signal with the method of data storage alignment and phase-locked frequency multiplica- tion.Provide the principle of method,realizing circuit and program design,and the test of precession signal indicate that the method absolutely fit the need of seeker tracking.The method is simple,cost least and widely use.
