Research on multi-target bearings-only tracking method based on passive sonar systems

This paper proposes a real-time multi-target tracking method for passive sonar systems based on bearing time record (BTR). Extremum detection and logical data association algorithm are employed in the method to detect and process the beginnings, tails, crossings and missing sections of tracks. As generated data is adopted in other works, data form field scenario is processed in this paper to evaluate practical qualification. As experimental results shown, this method have a well performance in practical environment.
