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

Abstract

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.
