摘要
对抗雷达关机是反辐射导弹(ARM)的一项重大关键技术。借助ARM方案弹道的平飞特性段,提出了采用纯方位无源定位(Bearing-Only)技术结合有控制输入的扩展卡尔曼滤波估计方法(EKF)解决ARM被动+捷联惯导复合制导方案为抗目标雷达关机所必须建立准确的惯性基准轴这一技术难题。仿真结果表明这种解决方案可以有效地增强ARM的抗关机能力。
The antagonism against the radar stopping radiating is a key technology of the anti-radiation missile. Base on the flat flying characteristic of ARM projected trajectory, Bearing-Only combined with extended Kalman filter （EKF） arithmetic is presented to build the exact inertial axis that is necessary for the passive radar homing combined with the strap-down inertial guidance used on ARM to work against target radar switching off. Simulation results show that this resolvent is effective to enhance the ability of ARM against radar stopping radiating.
