采用电视制导的小型空地导弹要实现大落角攻击,主要受导引头框架角、导弹飞行高度、导弹可用过载三个方面的约束。常用的大落角导引律有框架角门限比例导引、过重力补偿比例导引和落角补偿比例导引等,设计与仿真结果对比表明,带过重力补偿的比例导引方案需用过载小,可使导弹在进行大落角攻击时满足各方面的约束条件。

There are three constraints on a miniature TV guided missile for attacking target with a large attack angle, they are the frame angle of the seeker, the missile flight attitude and the overload can be used. PNG with frame angle threshold, over-gravity compensation or impact attitude angle compensation are the guidance laws usually used to get large attack angle. Simulation results indicate that the PNG with over gravity compensation asks for least overload of the missile, and large attack angle within all of the constraints can be achieved.
