Advanced guidance law design based on the information-set concept

Addresses an approach to guidance algorithm design based on the concept of information sets (IS). As an example of guidance problem/spl Gamma/ a model of defense scenario against a reentering ballistic missile is considered. In this scenario/spl Gamma/ a maneuverable decelerating target is to be destroyed by a hit-to-kill interceptor fitted with an IR array seeker and lateral impulse thrusters. The key element of the proposed approach is a description of the "interceptor-target" system state by means of IS. The results of Monte Carlo tests of the developed algorithm are presented.
