Abstract: Single missile-borne radars are unable to effectively cope with false target jamming in a complex battlefield environment due to a single angle of view, a lack of information, and low anti-jamming efficacy. A method against false-target jamming is thus proposed based on an active/passive missile-borne radar network. This method considers the position error of the missile-borne radar. When the track first begins, angle information is used to identify the measurements of active and passive radar seekers, and some false targets are eliminated. The track initiation of passive missile borne radar is assisted by successfully correlated measurements of the active missile borne radar. Then, the targets are tracked separately by the active and passive missile-borne radars. During track correlation, tracks are associated to identify and eliminate the remaining false targets. Simulation results show that the proposed method can effectively suppress the false-target jamming based on deceptive distance while ensuring high real target discrimination probability.
