摘要

为了提高复杂环境下主动雷达/红外复合制导系统的目标跟踪精度及抗干扰性能，充分发挥其观测数据的优势，提出一种状态-角度联合估计的信息融合方案。远距离条件下，利用容积卡尔曼滤波算法、卡方分布理论及信息融合算法，完成飞行器-目标相对状态估计、传感器受扰状态判断以及目标一致性关联与融合。近距离条件下，基于卡尔曼滤波算法完成角度滤波修正和角度融合估计。仿真结果表明：所设计的方案和算法能够有效剔除虚假信息，同时可以可靠获取传感器信息缺失条件下的稳定高精度导引信息，该结果可为复杂环境下的对抗决策以及目标精确打击提供依据。

Abstract

To improve the target tracking accuracy and anti-jamming performance of the active radar/infrared composite guidance system in complex environments and take full advantage of its observation data， this paper proposes an information fusion scheme based on state-angle joint estimation. Under long distance conditions， the volume Kalman filter algorithm， chi-square distribution theory and information fusion algorithm are used to complete aircraft-target relative state estimation， sensor disturbance state judgment， and target consistency correlation and fusion. Under the condition of close range， angle filtering correction and angle fusion estimation are completed based on the Kalman filter algorithm. The simulation results show that the scheme and algorithm proposed can effectively eliminate false information， and can reliably obtain stable and high-precision guidance information when sensor information is missing. The results can provide a basis for confrontation decision-making in complex environments and precise strikes against targets.

Key words： target tracking; anti-jamming; volume Kalman filter; state estimation; consistency
