摘　　要：角闪烁是影响毫米波末制导雷达角跟踪精度的主要因素之一,可能致使脱靶量增加,甚至导致目标丢失。然而目前关于角闪烁的研究主要基于理论分析、建模和仿真,试验研究相对较少。本文首先简述了角闪烁产生的机理,分析了角闪烁的特征,然后总结了抑制角闪烁的常用方法,并阐述了高分辨雷达抑制角闪烁的原理,开展了毫米波单脉冲雷达角闪烁试验,最后利用室内试验结果验证了高分辨可有效抑制目标上多散射中心间相互干涉引起的角闪烁。Angular glint is one of the most key factors influencing angular tracking precision of millimeter wave monopulse radar, which may increase miss distance, even result in target losing. However, the current researches on angular glint mainly include theory analysis, modeling and simulation, but less experimental study. Firstly, this paper analyses the generation mechanism and characteristics of angular glint. Secondly, the principle of suppressing radar angular glint based on high range resolution profile is explained. Finally, the performance of radar angular glint suppression by means of high range resolution profile is verified by experimental data.
