A New Estimation Method for Burnout Point Parameters of Ballistic Missile Based on Closest Distance Method

Abstract

The estimation for burnout point parameters of ballistic missile has not been solved systematically. Under the condition without prior information, the paper starts from the change of motion rules caused by the changes of force before and after burnout, and uses the combination of track time cross-extrapolation and the closest distance search to estimate burnout point parameters of target. results show that the closest distance search method is evidently better than the ordinary methods.
