摘　　要：针对传统反辐射导弹由于测角体制缺陷无法有效对抗诱偏干扰的问题,利用空间谱估计的角度测量高分辨能力,提出了一种复合测角系统。该测角系统包含单脉冲、空间谱估计两个测角单元,通过对两个测角单元测量数据的融合获得最终测角结果。空间谱估计测角单元的超分辨特性弥补了单脉冲测角单元角度分辨能力弱的缺陷;与单脉冲测角结果融合,空间谱估计测角单元的相位模糊、测角精度差等问题得到解决。通过复合测角系统,反辐射导弹利用空间谱估计实现角度超分辨,对抗诱偏系统成为可能。最后的仿真实验验证了采用这种测角体制的反辐射导弹的可行性和抗诱偏能力。To overcome the shortcomings of the traditional anti-radiation missiles （ARM） for anti-decoy, a complex angle measuring system is proposed in this paper, using high-resolution measurement capability of the spatial spectrum direction-of-arrival （DOA） estimation. The complex angle measuring system consists of monopulse angle and spatial spectrum estimation, the two angle-measuring units. The final data is got through fusing the measuring data of the two units. The super-resolution feature of spatial spectrum estimation angle-measuring unit makes up the defects of the monopulse angle- measuring unit to distinguish the targets; the phase fuzzy and poor accuracy in the spectrum estimation angle-measuring unit are resolved by fusing with data of the monopulse angle-measure unit. Through the complex angle measuring system, ARM can use the super-resolution features of spatial spectrum DOA estimation. It is possible that ARM withdraw the active decoy system . Finally, the simulation test verifies that the ARM with using the complex angle-measuring system is the feasibility and anti-decoy capacity.
