摘要:

角反阵列能形成与舰船目标相似的高分辨一维距离像(high resolution range profile, HRRP),给现有雷达识别提出了严峻挑战,但角反阵列和舰船目标随着观测角度变化的规律有差异,据此提出了双雷达HRRP相似度特征,用于鉴别角反阵列和舰船目标。电磁仿真结果表明,该特征有效刻画了角反阵列和舰船目标HRRP随视角变化的稳定性差异,在双雷达视线夹角大于60°和-2 dB信杂比条件下,基于双雷达HRRP相似度特征的角反阵列和舰船目标识别正确率可以达到99.07%。

Abstract:

Corner reflector arrays can generate high resolution range profiles (HRRPs) similar to those of ship targets, posing significant challenges to existing radar recognition systems. However, the variation patterns of HRRPs for corner reflector arrays and ship targets differ with observation angles. Leveraging this distinction, this paper proposes a dual-radar HRRP similarity feature to discriminate between corner reflector arrays and ship targets. Electromagnetic simulation results demonstrate that this feature effectively captures the differences in HRRP stability under varying viewing angles for the two target types. When the line-of-sight angle between two radars exceeds 60°and the signal-to-clutter ratio (SCR) is -2 dB, the recognition accuracy for distinguishing corner reflector arrays from ships reaches 99.07% using the dual-radar HRRP similarity feature.
