基于多机编队有源组网探测的多目标跟踪算法

摘要

针对空战背景下低可观测目标的跟踪问题，提出了基于多机编队有源组网探测的多目标跟踪算法。该算法根据多平台信息分配模型与评分，设计基于评分的求解方法选取可行分配模式，合成等效测量；结合多假设思想，以航迹树的形式组织可能目标，通过设计航迹树的分支与删除策略，实现虚警的剔除以及航迹的起始、维持与终结，通过设计航迹树显示逻辑，显示当前时刻目标的航迹批号与运动参数。仿真结果表明，提出的算法能够在低可观测条件下有效并稳定地跟踪多个目标。%For multiple targets tracking under the condition of low detection probability,a new multi-target tracking algorithm based on networking airplanes was proposed.A second-best technique to obtain equivalent measures according to dynamic allocation model and scoring functions were designed.Then the algorithm re-moved the false alarms,initialized the tracks,maintained the tracks and terminated the tracks by multiple hy-pothesis testing.Meanwhile,display logic was applied to show the state estimation and the batch of targets at each scanning.Simulation results showed that the proposed algorithm could efficiently and steadily track multi-ple targets under the condition of low detection probability.
