摘要
针对毫米波导引头转入跟踪后经常出现丢失目标的问题,提出了一种适用于窄波束角毫米波导引头目标再捕获的定位方法。首先,利用弹上惯性导航装置提供的导弹位置信息、姿态信息以及导引头提供的弹目距离等信息求解感兴趣目标的位置信息;然后,导引头根据定位信息进行二次扫描搜索。所提算法可显著缩短窄波束角毫米波导引头二次捕获目标的时间,以保证足够的末制导时间实现目标的有效打击。
Aiming at the problem that the millimeter waveguide(MMW)seeker often loses its target after turning into tracking,a target re-seizure and orientation method that is suitable for narrow beam angle millimeter waveguide seekers is presented.Firstly,the missile orientations and the attitudes that are obtained from the inertial navigation system,and the seeker to target distance that is obtained from the seeker are used to realize target location.Then,the second round searching and scanning are implemented,which is based on the target location.The consuming time of narrow beam angle millimeter waveguide for target re-seizure has been significantly decreased.The proposed method can provide sufficient time to achieve effective target attacking.
