基于AEKF的末制导雷达被动跟踪导引律设计

摘要

In order to improve the anti-interference ability of the anti-aircraft missile to realize tracking and interception.Based on the terminal guidance radar's operating principle.The features of the incoming target were acquired in active mode and the target was tracked in passive mode.The adaptive extended kalman filtering was applied in the navigation guidance and the anti-aircraft missile's trajectory was fitted out to achieve the tracking and interception.The simulation results showed the feasibility and availability of the guidance law,the adaptive extended Kalman filtering was better than the extended Kalman filtering in the respect of astringency.%为了提高防空导弹抗干扰能力,实现跟踪拦截来袭目标,基于主动模式获取目标特性后切换被动模式跟踪的末制导雷达工作原理,提出了一种利用自适应扩展卡尔曼滤波拟合出防空导弹弹道实现跟踪拦截的制导律.算例仿真证明了导引律的可行性和有效性,且自适应扩展卡尔曼滤波的收敛性能优于扩展卡尔曼滤波.
