3-D Biased PNG for Evasive Maneuver of Anti-Ship Missiles Against CIWS

Abstract In this paper, we propose advanced guidance laws for anti-ship missiles to enhance the survivability against ship-borne close-in weapon system in 3-dimensional space. The proposed guidance laws consist of a term of pure proportional navigation guidance to guarantee homing to target and a time varying bias term to cause evasive maneuver. As a time varying bias term, barrel-roll maneuvers are investigated. By using the Lyapunov stability theory, we prove the capturability of the proposed guidance laws against a non-maneuvering target. Evasion performance of the proposed guidance laws is compared to pure proportional navigation guidance via simulations.
