| Abstract:
In this paper, the missile guidance problem with desired impact angle is investigated based on a generalized-polynomial look-angle formulation. Shaped by a time dependent polynomial of arbitrary order, the look angle profile is given by a set of boundary constraints while one coefficient in the polynomial is preserved as the guidance gain. Since the impact angle problem in nonlinear domain is a challenging task, linearized engagement geometry is employed to establish the impact angle constraint, which determines the guidance gain. With the help of frame convention, the guidance gain is further updated continuously to perform in the nonlinear domain which leads to a closed-loop form of the guidance law. Moreover, a method to satisfy the look-angle constraint during the flight is proposed. Simulated cases are provided to demonstrate the effectiveness and robustness of the proposed guidance law.
