A BAYESIAN SOLUTION TO THE RE-ENTRY TRACKING PROBLEM.

Abstract

The differential equations of motion for a re-entry body are highly nonlinear near the region of maximum deceleration. Determination of the trajectory of such an object and accurate prediction of its impact point from radar observations is a difficult computational problem. This report presents a new procedure for re-entry tracking which makes use of Bayes estimation to obtain optimal approximations to the unknown re-entry body parameters. Preliminary experiments conducted on a hybrid computer have confirmed the basic feasibility of the method. (Author)
