一种末制导雷达抗拖曳式诱饵干扰新方法
Novel anti-TARD method for terminal guidance radar
摘要
Abstract
As an active deceptive jamming style,the towed Radar Active Decoy(TRAD)plays a crucial role in modern electromagnetic spectrum warfare.These TRADs modulate and retransmit radar signals to simulate target echoes,inducing radars to track stronger false targets,thereby providing self-defense protection for the aircraft.To address the vulnerability of terminal guidance radars to TRAD deception,this paper proposes a countermeasure method based on spatial morphological features.Since jamming signals cannot realistically replicate the spatial morphology of targets under wideband conditions,the proposed method enables effective target discrimination and anti-jamming imaging.First,a monopulse three-dimensional(3-D)imaging algorithm is employed to reconstruct the spatial distribution of strong scatterers in the radar's forward-looking region.Second,spatial filtering is applied to the imaging results to remove noise points and cluster the strong scattering point clouds.Finally,spatial morphological features are extracted from each point cloud cluster.A discriminator is then employed to perform target identification,resulting in an anti-jamming three-dimensional image of the target.Theoretical analysis and experimental results reveal significant spatial morphological differences between the false targets produced by the TRAD and the actual targets.These findings validate the effectiveness of the proposed method in countering TRAD jamming.关键词
