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 range-false-target deceptive jamming effectivelyand is also appropriate for non-jamming situation.Simulation results verify the application value of the technique.
