雷达导引头速度和角度跟踪互助算法设计

摘要

Active radar seeker technique has shown its mainstream status in modern tactical missile,while angle tracking and velocity tracking algorithms are important parts of radar tracking system. Tracking precision determines shoot precision. However,once radar seek-er was disturbed by velocity dragging jam,the measured value of velocity channel becomes unbelievable. Therefore,in order to detect ve-locity dragging jam in time for system target acquisition or target tracking phase,in it,algorithm of combined interactive angle/velocity tracking was designed. Angle channel information can be processed for velocity channel information correction,the tracking stability in disruption environment can be guaranteed. Whole algorithms were implemented in intact radar seeker system,whose validity and efficien-cy have been proved in simulation and infield test.%　　主动雷达导引是现代导弹的主流研究方向，而角度跟踪算法和速度跟踪算法则是主动雷达跟踪算法中的重要组成部分，其跟踪精度决定着雷达系统的制导精度。但是，当弹载雷达受到速度拖引干扰时，速度通道测量值就不再可信。为了在系统截获目标阶段，或者在目标跟踪阶段及时判断出速度拖引，文中进行了角度跟踪和速度跟踪的算法设计，解决了干扰环境下的跟踪稳定性问题，实现了算法软件在系统的验证试验，仿真及内场试验证明其算法具有可行性和有效性。
