A DENSE FALSE TARGET JAMMING SUPPRESSION METHOD BASED ON INTER-PULSE PHASE AGILITY WAVEFORM

As a typical form of jamming, long-range support jamming with full-pulse dense forwarding, which has both blanketing and deception effects, significantly degrades the target detection performance of radar. Since long-range support jamming lags behind the target, this paper utilizes the range-gating characteristics of the inter-pulse phase agility waveform. It exploits the differences in energy distribution within the range-Doppler domain to distinguish between jamming and the target, facilitating the separation and reconstruction of both jamming and the target through alternating projection. Simulation results validate that the proposed method accurately reconstructs both jamming and the target, leading to a significant improvement in the Signal-to-Interference-plus-Noise Ratio (SINR) in the scene of strong jamming.
