Method for Time-Varying Signal Detection in Control System of a Type of Missile

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.
