摘　　要：利用分布式主/被动成像探测系统探测到同一关键目标后,需要融合目标多源信息,综合主/被动成像探测器的不同定位精度,解算关键目标的精确空间位置。针对分布式主/被动成像探测系统成像体制不同、定位解算模型不同、定位精度不同的问题,本文提出一种统一的目标空间协同定位数学模型,并采用线性加权-遗传算法对该数学模型进行联立求解,获得目标空间协同定位结果。仿真试验结果表明,本文构建的目标空间协同定位数学模型以及基于线性加权-遗传算法的目标空间位置求解方法,为分布式主/被动成像探测系统的目标空间协同定位问题提供了统一的模型架构与解算途径,同时也解决了不同成像体制探测器带有不同定位误差情况下的目标多源信息融合问题,在分布式无人机集群、分布式巡航导弹群以及分布式战斗机集群对重要目标的探测任务中,能够有效提高探测系统的精确探测、制导、打击、拦截能力。When using the distributed active/passive imaging detection system to detect the same key target, it is necessary to fuse the multi-source information of the target, integrate the different positioning accuracy of active/passive imaging detector, and calculate the precise spatial position of the key target. Aiming at the problems of different imaging systems, different positioning solution models and different positioning accuracy of distributed active/passive imaging detection system, a unified target space collaborative positioning mathematical model is proposed in this paper, and the linear weighted genetic algorithm is used to solve this mathematical model to obtain the target spatial collaborative positioning results. The simulation results show that the mathematical model of target spatial collaborative positioning constructed in this paper and the target spatial positioning method based on linear weighted genetic algorithm provide a unified model and solution for the target spatial collaborative positioning problem of distributed active/passive imaging detection system. Meanwhile, it also solves the problem of target information fusion when detectors of different imaging systems have different positioning errors. During the detection mission of key target by distributed UAV cluster, distributed cruise missile cluster and distributed fighter cluster, the model and algorithm proposed in this paper can effectively improve the accurate detection, guidance, attack and interception ability of the detection system.
