Abstract

This paper investigates the impact-angle-constrained guidance problem for anti-ship missiles equipped with strapdown seekers with limited field-of-view. A homing guidance law with switching logic is proposed to satisfy impact-angle constraint and field-of-view limitation. Based on optimal control theory, the impact-angle-constrained term is derived analytically. Then a biased term is designed for restricting look angle when it tends to exceed the pre-designed boundary value. Numerical simulation results demonstrate that the proposed guidance law can work perfectly with different impact angle constraint or look angle limit. Furthermore, the proposed approach requires smaller acceleration capacity and less energy consumption than the other two comparative methods.
