极化域-空域联合估计在反辐射导弹抗诱偏中的应用研究

提出了将极化阵列应用到反辐射导引头上,导引头利用目标与诱饵的极化差异,采用极化域-空域联合估计方法抗诱偏。首先,利用波达方向矩阵法,估算出雷达与诱饵的空间二维到达角和极化参数,将估算出来的二维到达角信息为反辐射导引头提供导引,极化参数用来鉴别雷达与诱饵,从而达到抗诱偏的目的。然后,结合导弹运动方程及导引方程对反辐射导弹抗三点源诱偏进行了全弹道数字仿真,并且采用Monte-Carlo方法对全弹道仿真进行了多次实验,仿真结果证明了将极化域-空域联合估计应用于反辐射导引头抗诱偏的可行性。

Research on Anti-decoy in Anti-radiation Missile Using Joint Estimation of Polarizational and Spatial Domains

The study proposed the polarization array in anti-radiation seeker, which uses joint estimation of polarizational and spatial domains anti-decoy by the differences of the target and decoy. At first, it estimated DOA (direction of angle) and polarimetric parameters of radar and decoys, the DOA supply to guide the ARM and the polarimetric parameters apply to discriminate the radar or decoys, for the purpose of preventing decoy. Then, the all-trajectory simulation on ARM against three point sources bait is accomplished by combining ARM motion equation and guide equation. Many experiments on all-trajectory simulation are done by Monte-Carlo. The simulation results demonstrate the effectiveness on anti-decoy in anti-radiation missile using joint estimation of polarizational and spatial Domains.
