Impact Angle Control Law with Sinusoidal Evasive Maneuver for Survivability Enhancement

Impact Angle Control Law with Sinusoidal Evasive Maneuver for Survivability Enhancement In this paper, a new guidance law to enhance the survivability of anti-ship missiles against anti-air threats is presented. Sinusoidal maneuver acceleration is considered as a feed-forward input to a first-order lag system dynamics on the plane. Subject to this system dynamics a planar optimal guidance law for a stationary target 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. Enhanced survivability with the proposed law against anti-air missiles is verified via numerical simulations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical & Space Sciences Springer Journals

Abstract

In this paper, a new guidance law to enhance the survivability of anti-ship missiles against anti-air threats is presented. Sinusoidal maneuver acceleration is considered as a feed-forward input to a first-order lag system dynamics on the plane. Subject to this system dynamics a planar optimal guidance law for a stationary target 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. Enhanced survivability with the proposed law against anti-air missiles is verified via numerical simulations.
