摘要/Abstract

摘要： 针对单部弹载雷达在欺骗式假目标干扰的情况下存在视角单一、信息量少、难以有效抗干扰的问题，提出主被动异构弹载雷达组网抑制假目标干扰方法。该方法考虑了弹载雷达位置误差，在航迹起始阶段利用角度信息对主动和被动雷达导引头的量测量进行两两关联鉴别，从而剔除部分假目标，并使用关联成功的主动弹载雷达量测信息辅助被动雷达进行航迹起始；在航迹关联阶段，主动与被动弹载雷达分别对目标进行跟踪滤波，通过序贯航迹关联算法再次鉴别剩余假目标。仿真结果表明，该方法能够在保证较高的真实目标鉴别概率条件下对距离欺骗式假目标干扰进行有效抑制。

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.
