System for Bearings-Only Contact State Estimation Using Recurrent Neural Networks

摘要

A system for bearings only contact state estimation in response to target bearingand ownship speed and course information provided for a plurality of observation legs at successive points in time, includes a plurality of neural networks and a data fusion circuit. Each of the neural networks generates range normalized parameter estimate information for one of the observation legs in response to target bearing and ownship speed and course information for an associated one of the observation legs, provided thereto at each point in time and information generated for the previous point in time. The data fusion system receives the range normalized parameter estimate information from the neural networks and generates the contact state estimate in response thereto.
