Target tracking algorithm in radar reference coordinates using coupled filters

This paper proposes a tracking algorithm in radar reference coordinates (RRC) using coupled filters. Tracking filters are discussed from the viewpoint of the fundamental problems of both modeling accuracy and real-time computational requirements. In most cases, if one becomes better, another gets worse. A trade-off between them always exists. Then our algorithm satisfies these conditions as much as possible by use of coupled filters. Through several simulations, validity of our algorithm has been confirmed in tracking non-maneuvering target.
