针对分布式干扰下雷达对目标的检测概率降低导致跟踪航迹不连续的问题,提出了一种分布式干扰下分布式雷达网目标跟踪技术。首先将组网各雷达跟踪滤波后的航迹数据上报到融合中心进行时空对准,然后在融合中心对分布式干扰下上报的不同航迹类型进行关联检验,最后对通过关联检验的航迹滤波融合。该技术能提高分布式干扰下目标跟踪航迹的连续性和稳定性,仿真结果证明了该技术的可行性和有效性。
Under distributed jamming, radar tracking is discontinuous due to low detection probabili- ty, and a target tracking technique for distributed radar network is proposed. Firstly, transforming the tracks of radar network to fusion center and completing the time-space alignment. Then, association and inspection are made for different types of track in the fusion center of radar network. Finally, the tracks passed the inspection are fused. The technique can enhance continuity and stability of radar network target tracking under distributed jamming. Simulation results verify the feasibility and validity of the pro-posed technique.
