Multisensor tracking of ballistic targets

摘要: ABSTRACT This paper addresses the multisensor tracking of targets but considers only special case on a ballistic trajectory.The scenario consists two radars tr&king same target One these periodically sends track to other radarfor fusion with generated by recipient. A algorithm for is derived. Thisalgorithm exercised and illustrated Sensor Fusion Architecture Model (SFAM) computer program. Since therepeated ofballistic trajectories results in correlation that must be removed preserve optimality resul-taut estimate, an requires preservation last update error covariance matrix from anotherKalman Filter (1(F) also presented. These data then are used decorrelate inputs originating at same-source KF.Keywords: missile, Kalman (KF), radar, sensor fusion, 1.
