摘要
针对传统反辐射导弹(anti-radiation missiles,ARM)无法有效对抗有源诱偏干扰与雷达辐射信号控制的问题,提出了一种对抗环境下反辐射导弹瞄准点估计方法:通过构造空间谱测角与单脉冲测角复合测角系统,测量信号波达角,使ARM具备诱偏条件下的弹目信息测量能力;利用高精度的捷联惯导系统(strapdown inertial navigation system,SINS)实时获取ARM自身位置信息,通过量测转换、异常值剔出、目标位置估计等数据处理过程获取目标精确位置,修正瞄准点,剔除了量测粗大误差,抑制了量测随意误差。通过本文介绍的反辐射导弹瞄准点估计方法,ARM可在对抗的环境下获取准确的瞄准点,使ARM有效对抗有源诱偏干扰与雷达辐射信号控制成为可能。仿真实验验证了方法的可行性和其对抗能力。
To confront active decoying disturbance and radar radiation signal interference are key problems for improving operational efficiency of anti-radiation missiles （ARM）. An aiming point estimation approach is proposed in this paper. In the approach,the complex angle measuring system,which consists of monopulse angle and spatial spectrum estimation to measure DOA,can get missile-to-target information in the decoy environment based on the high-resolution of spatial spectrum estimation. ARM information can be acquired through the high-accuracy strapdown inertial navigation system （SINS）. Target exact location can be acguired by removing gross error and measurement conversion. ARM aiming point is adjusted by the exact target location. When the new target location can not be acquired,aiming point is attacked by self-guidance of SINS with high probability. Finally,the simulation tests verify that the composite guidance approach is the feasibility and anti-electromagnetic-confrontation capacity.
