Data Association Algorithm for Passive Sensor System

Abstract

This paper mainly study angle-measurement based data association algorithm to overcome the existing problems in the applications of traditional association approaches forbearing-only target locating and tracking system. By deeply analyzing different data association algorithms and target motion characteristics in bearing-only coordinate, suitable angle-measurement based association algorithm is presented.As the results, the two-dimensional bearing-only measurement confirming efficiency of real target is improved and false tracking with the dense clutter is limited. The application of this algorithm has effectively resolved the track association problem of the bearing-only tracking using a single passive sensor. The application of the proposed approach in a simulation system proves its effectiveness and practicability.
