摘要

In this Note, a new impact angle control optimal guidance law has been developed for missiles with arbitrary velocity profiles against maneuvering targets. The guidance law development is based on the linearization of kinematics around the zero-effort collision triangle, which has been newly introduced for impact angle control problems and behaves like an equilibrium point in the engagement dynamic system. The best guidance performance has been shown in a numerical simulation work when the reference line is chosen in such a way that the distance between the current missile position and the corresponding vertex of the zero-effort collision triangle is fully captured by a guidance variable. Many important practical questions such as how it performs under the presence of uncertainty in the information of future target maneuver and missile velocity profile remain to be addressed.
