摘　　要：在空空导弹制导引信优化控制的研究中,为了提高一体化引信的引战配合起爆控制精度,提出了红外成像/激光测距一体化引信异步信息融合方法,在分析红外成像和激光测距两种探测模式的测量信息在种类及时序上的差异的基础上,利用数字系统控制方法实现了红外成像/激光测距测量信息的同步关联,给出一种UKF一体化引信集中式信息融合滤波算法。通过仿真表明:提出的方法能有效提高引信系统复杂交会条件下的起爆控制预测算法精度,实现引战配合精确起爆控制。The paper put forward an asynchronous information fusion algorithm of GIF based on imaging guid- ance/laser ranging to improve the burst control accuracy. Based on analyzing the detecting information differences of the two detection modes in type and timing, the information was synchronized using digital system control method, and a GIF centralized fusion algorithm based on UKF was put forward. The simulation results show that the algorithm can effectively raise the accuracy of burst control predicting algorithm of the fuse system under complicated encounter conditions, and realize fuse and warhead matching precise burst control.
