A Large Attack Angle Guidance Law for Miniature Air-to-ground Missile

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.
