摘要
距离假目标欺骗干扰下,雷达接收到高逼真度的虚假信号,从信号层面无法有效将其滤除,致使虚假信号进入雷达数据处理器形成虚假点迹,进而经过滤波跟踪后形成虚假航迹。为此,提出了基于雷达网数据融合的跟踪技术。首先,对雷达网中各部雷达的位置量测数据分别进行预处理;然后,在融合中心进行关联处理,计算出等效位置量测,实现目标的精确定位;最后,实现对目标跟踪。该技术能有效克服距离假目标欺骗的干扰,也适用于无干扰的情况。经过仿真验证,该技术具有一定的应用价值。
In the presence of range-false-target deceptive jamming,the radar receives false signal with high fidelity,which is difficult to be filtered out effectively from the signal level. The false signal may enter into radar data processor and form false plots,and then form false tracks after filtering and tracking. To solve this problem,a target tracking technique is proposed based on radar network data fusion. Firstly,the position measurement data of each radar in the radar network are preprocessed respectively. Then,correlation processing is carried out in the fusion center,and the equivalent position measurements are obtained to realize accurate positioning for targets. Finally,target tracking is realized. The technique can overcome rangefalse-target deceptive jamming effectively,and is also appropriate for non-jamming situation. Simulation results verify the application value of the technique.
