The current battlefield environment is increasingly harsh, and the target characteristics increasingly complex and changeful. For anti-tank missiles, the place thickness of the armored target, the angle and the reactive armor can significantly affect the missile damage efficiency. To improve the missile damage to the target, an easy-to-implement, engineering-applicable, wide-range impact control method is proposed with missile full-distance inter-visibility. Adopting the control scheme combining the midcourse guidance trajectory strategy favorable for missile seeker full-distance inter-visibility with the optimal terminal guidance proportional navigation strategy, it achieves impact angle control of a wide range (20 \(^\circ \) –90 \(^\circ \) ) of the missile. According to verification by simulation and flight test, the angle control meets the design requirements of the weapon system, effectively improves the damage to targets.
