摘要
给出一种导弹控制系统中时变信号的检测方法。首先分析导弹控制系统中的3种电信号:飞行偏差信号、飞行距离信号及滚转方位信号。采用具有采样保持电路的双极性A/D转换器进行时变电信号分析,而子电路原理分析则涉及极性比较器、绝对值电路,以及A/D网络开关,由此得出结论:导弹控制系统中多为具有极性变化的时变信号。
The article proposes a method for time-varying signal detection in one missile＇s control system. First, analyzed three electronic signals of missile control system： flight deviation signal, flight distance signal and azimuth signal of rolling. In the process of analysis for time-varying signal, the bipolar A/D converter had sampling and holding circuit is used; and during sub-circuit theory analysis, the polarity comparer, absolute value circuit and A/D network switch are used. Analysis concluded signals in missile control system are mostly time-varying signal with polar variations.
