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。
針對空戰揹景下低可觀測目標的跟蹤問題,提齣瞭基于多機編隊有源組網探測的多目標跟蹤算法。該算法根據多平檯信息分配模型與評分,設計基于評分的求解方法選取可行分配模式,閤成等效測量;結閤多假設思想,以航跡樹的形式組織可能目標,通過設計航跡樹的分支與刪除策略,實現虛警的剔除以及航跡的起始、維持與終結,通過設計航跡樹顯示邏輯,顯示噹前時刻目標的航跡批號與運動參數。倣真結果錶明,提齣的算法能夠在低可觀測條件下有效併穩定地跟蹤多箇目標。

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.
