Study on practical application of a guidance law for overhead-attack

This paper investigates a new concept of "overhead-attack". Firstly, a guidance law with the terminal angle restraint proposed, which is given by establishing the right Hamiltonian. Furthermore the practical application in Engineering is also given in this paper. The guidance law provides a trajectory scheme with terminal angle restraint, which is efficient for penetration bombs or missiles. Simulations show that the guidance law is effective for overhead-attack, which requires higher overload for the bomb as the increase of the terminal angle. Secondly, this paper investigates four important factors for penetration bombs: the guidance system, the homing head, the range, and the maneuverability. The analyses of those four factors are also given. It has been proven that this guidance law works effectively for a bomb that needs to attack an "overhead" target. It confirms that the method works in practical application.
