针对空中平台末端防御系统对来袭导弹威胁感知的高实时性和高准确性需求,文中提出一种基于多源威胁信息的机载末端导弹融合与识别方法。首先构建高实时、快速关联融合算法模型,并根据被动传感器融合结果引导雷达探测,获取导弹距离与速度信息,给出准确、可靠的导弹运动态势,在此基础上,根据Dempster-Shafer(D-S)证据理论对目标属性进行综合识别,构建包含状态与属性的导弹完整航迹信息,支撑机载末端防御决策。通过仿真实验验证表明,所提出的方法能够实时生成导弹感知综合态势画面,并具有较好的导弹识别性能。

Aiming at the high real-time and high accuracy requirements of the air platform terminal defense system for the threat perception of incoming missiles, an airborne terminal missile fusion and recognition method based on multi-source threat information is proposed. Firstly, a high real-time and fast association fusion algorithm model is constructed. According to the passive sensor fusion results the radar detection guidance is realized, so as to obtain the missile distance and speed information. Accurate and reliable missile movement information can be obtained. The attributes are comprehensively identified based on Dempster-Shafer (D-S) evidence theory, and the complete trajectory information of the missile including the status and attribute is constructed to support the airborne terminal defense decision-making. The simulation experiment shows that the method proposed in this paper can generate the comprehensive situation picture of missile perception in real time, and has better missile recognition performance.
