Midcourse Guidance Strategies for Exoatmospheric Intercept

摘要

This paper considers the interception of an exoatmospheric target with a ship-based interceptor which employs both midcourse and terminal guidance. Before and during the midcourse phase of flight the target is tracked with a ship-based radar. With target state estimates derived from the radar measurements, the interceptor is launched at the expected intercept point. The inevitable intercept point prediction errors are reduced during the interceptor's flight with midcourse guidance updates from the ship. When the interceptor's seeker acquires the target, noise free terminal guidance information is assumed for guiding on the actual target. The purpose of this paper is to briefly investigate various midcourse guidance strategies which will influence the missile's terminal performance.
