A distributed multiple warships bearings-only tracking algorithm

A distributed multiple warships bearings-only tracking algorithm is presented. By attribute association and space association, this algorithm can do the location association of multiple warships passive ESM sensors, it also adopts the time-varying sampling modified gain extended Kalman filter (MGEKF), and shipborne ESM equipment of multiple warships is used to distributed bearings-only tracking fusion of multiple maritime moving emitters. Computer simulation results proved that this algorithm can satisfy the needs of practical applications.
