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.
