基于空间谱估计的反辐射导弹抗有源诱偏技术

相较传统反辐射导弹导引头无法有效抗有源诱偏干扰,提出改进的ESPRIT空间谱估计算法,可有效提高导引头角分辨力。理论仿真表明,改进算法可有效地使导引头较早分开雷达和诱饵辐射源,提高导引头抗诱偏能力。

Spatial spectrum estimation based anti-active-decoying technology for anti-radiation missiles

An reformative ESPRIT algorithm which using the spatial spectrum estimation method is presented in this paper to improve the angle resolution abilities of ARM seeker,so as to resolve the problems that the traditional anti-radiation missile （ARM） seeker can’t counter the jamming decoys effectively. Simulation results indicate that the improved algorithm can effec-tively separate the radar and decoying radiation source in the early time,thus the anti-jamming ability of ARM seeker is en-hanced.
