Apparatus and method for long term tracking for ASW applications

An apparatus and method are disclosed that provide target motion analysis with the ability for having long-term tracking. The apparatus and method provide a leg builder program that monitors successive positional updates from a target and converts the updates into a leg format. The leg format consists primarily of start time, latitude/longitude, time on leg, and end latitude/longitude. The leg format is continuously updated so long as the course of the target is steady. The leg format further embodies routines that provide for a spherical earth model and also for handling unstable course and speed conditions from a target.
