摘要:

针对欺骗式假目标干扰,提出一种利用分布式融合结构主/被动雷达网的距离欺骗式假目标鉴别算法.首先利用主动雷达中的量测值来联合被动雷达进行航迹起始,并在航迹起始阶段剔除部分假目标; 之后,主动雷达和被动雷达独立地对目标进行跟踪滤波; 对于主动雷达中已形成稳定航迹的假目标,利用航迹关联的方法将其剔除.仿真结果表明,这种方法可以在保证真实目标鉴别概率的前提下,对欺骗式假目标进行有效的鉴别,降低主/被动雷达网的被欺骗概率.

Abstract:

A false target discrimination method is proposed for active/passive netted radar at different sites with distributed fusion architectures to anti distance false-target deception jamming. First, the measurements in active radar are used as the supplementary for the track initiation of passive radar, in which some false-targets are eliminated. Then, the targets are tracked independently in active radar and passive radar. Finally, track association between active radar and passive radar is applied to discriminate and eliminate the false-targets which have been maintained in active radar. Simulation results verify the ability of the method proposed to reject the false targets effectively and reduce the cheated probability of active/passive netted radar, while still keeping the high recognition probability of the true target.

Key words: netted radar, track initiation of passive radar, track association, false-target deception jamming
