Target Track Crossing Prediction/Detection

Abstract

A method and system are provided for predicting and detecting the crossing of two target tracks in a bearing versus time coordinate frame. The method/system uses a series of periodic bearing measurements of the two target tracks to determine a bearing rate and a projected intercept with a bearing axis of the bearing versus time coordinate frame. A crossing time (t sub c) for the two target tracks is determined using the tracks bearing rates and projected intercepts. A prediction that the two target tracks will cross results if a first inequality is satisfied while a detection that the two target tracks have crossed results if a second inequality is satisfied.
