摘要：

航天发射任务中, 单部雷达存在测量视角不全、部分航迹抖动等问题, 难以形成高精度连续稳定航迹, 分布式多站视角下多雷达、多目标航迹处理成为航天发射场的紧迫课题。针对此问题, 提出一种航天发射任务分布式多站实时航迹处理方法。首先, 针对多部空间位置不同、数据率不同的雷达, 完成测量航迹预处理, 解决不同平台协同探测时空不统一的问题。之后, 针对多部雷达密集交错航迹提出一种多尺度航迹关联算法, 通过弹道落点粗聚类和加权距离精聚类在降低计算量的同时提升关联稳定性。最后, 采用凸组合融合算法实现多部雷达多目标航迹有效融合。实际应用结果表明, 所提方法能发挥多雷达集群体系探测的优势, 有效解决航天发射任务分布式多站中多雷达、多目标航迹关联与融合问题。

Abstract:

In space launch mission, it is difficult to measure a high-precision continuous and stable track due to the problems such as incomplete measurement viewing angle and partial track jitter of single radar. Multi-radar and multi-target track processing with distributed multi-station viewing angle become an urgent task for space launch sites. To solve this problem, a distributed multi-station real-time track processing method for space launch mission is proposed. Firstly, the measurement track pre-processing is completed for multiple radars with different spatial positions and data rates to solve the problem of spatio-temporal disunity of cooperative detection by different platforms. Then, a multi-scale track association algorithm is proposed for the dense interlacing track of multiple radars. The rough clustering of ballistic drop points and weighted distance fine clustering are used to reduce the computation and improve the correlation stability. Finally, convex combination fusion algorithm is used to realize the effective fusion of multi-radar and multi-target track. The practical application results show that the proposed method can give full play to the advantages of multi-radar detection system, and effectively solve the problem of multi-radar and multi-target track association and fusion in the distributed multi-station space launch mission.

Key words: distributed multi-station, multi-target data processing, track correlation, track fusion
