Abstract: Aim To apply homing guidance to rotary antitank missiles. Methods The feasibility analysis, loop of guidance head analysis and controller optimum design and so on were given, a new selection method of object function was presented, and realization ways of controlling rotary missile were studied. Results Above analysis and design are applied to some kind of rotary antitank missile, results of simulation show these methods can meet the expected technique requirements. Conclusion Homing guidance may apply to rotary antitank missiles.
