Abstract

A linear quadratic guidance law that enables imposing a required heading angle and an angle of attack is presented. This guidance law is derived using the optimal control methodology. This new guidance law is dependent on a unique zero-effort heading angle error and also on a variable denoted as zero-effort angle of attack. It is shown that this new guidance law enables an accelerating interceptor to fly towards the target along a straight line, after the initial heading error is nulled. The performance of the proposed guidance law is investigated using a nonlinear two-dimensional simulation of the missile's relative kinematics for an exo-atmospheric engagement. A dynamics free model of the target, perfect state information, and no control saturation are assumed. It is shown that compared to proportional navigation the proposed guidance-to-collision law improves the capture zone.
