Abstract
In this paper, a new guidance law to enhance survivability of anti-ship missiles against anti-air threats is presented. Sinusoidal maneuver acceleration is considered as a feed-forward input in a 1st-order lag system dynamics on the plane. Subject to this system dynamics a planar optimal guidance law is then derived to achieve zero miss distance and a specified impact angle, while minimizing the control effort. By independent application of this planar law for homing guidance on the vertical and the horizontal plane, three-dimensional evasive guidance is easily synthesized. The phase difference as well as the magnitude and frequency of the sinusoidal acceleration inputs for the vertical and the horizontal guidance is the design parameter to shape the three-dimensional spiral or barrel-roll evasive maneuver pattern. Evasive performance of the proposed law against anti-air missiles is verified via numerical simulations.
