多假目标欺骗干扰下组网雷达跟踪技术

针对距离多假目标欺骗干扰下的组网雷达跟踪,提出了一种基于同源量测融合的跟踪技术.该跟踪技术包括同源量测融合、多目标跟踪两部分.同源量测融合相当于对所有量测进行预处理,其关键在于同源量测自适应检验门限的设计.通过该预处理,输入的假目标的量测数目大大减少,且问题简化为单雷达的多目标跟踪.多目标跟踪中,根据航迹优先级顺序依次进行数据关联.该跟踪技术使得组网雷达可以有效剔除假目标,并更精确的跟踪真目标.仿真结果证明了该技术的可行性和有效性.

Tracking Technique for Radar Network in the Presence of Multi-Range-False-Target Deception Jamming

In the presence of multi-range-false-target deception jamming,a tracking technique is proposed for radar network,which is based on the fusion for the same source measurements.The technique involves two steps:fusion for the same source measurements and multi-target tracking.The fusion for the same source measurements is a preprocessing of the technique.The key of the fusion is design of an adaptive threshold for test the same source measurements.The preprocessing can not only decrease the number of the false targets' measurements,but also simplify the problem as multi-target tracking for single radar.In multitarget tracking,data association is performed in sequence of track's priority.Using this tracking technique,radar network can reject false targets effectively,and track the true targets more precisely.Simulation results verify the feasibility and validity of the proposed technique.
