摘要/Abstract

摘要：

分布式雷达网相对于单站雷达系统而言, 可以通过信息融合、协同探测等技术获得目标探测性能的提升。然而实际应用中, 目标相对于各个雷达站距离和视角通常不同, 往往存在某些雷达站由于信噪比较低无法捕获成功。针对上述问题, 充分依托分布式雷达网信息共享的优势, 提出一种多帧联合航迹起始方法。首先将已经成功建立目标航迹的雷达站获取的跟踪信息, 传递至尚未发现目标的雷达站, 并基于该跟踪信息建立预测波门, 设计预测波门内的多帧联合检测方法, 最终根据检测结果完成目标航迹起始。仿真试验表明, 所提方法可以实现航迹起始性能的提升。

Abstract:

Compared with single radar systems, distributed radar network can achieve target detection performance improvement, via techniques of information fusion, cooperative detection, et al. However, in real applications, considering the difference of target distance and viewing aspect relative to different radar sites, there usually exists some radar site that cannot capture the target because of low signal to noise ratio. For the above problem, the advantage of information sharing in the distributed radar network is used sufficiently. And a multi-frame track initiation method is presented. Firstly, the tracking information from the radar site that already established target track is sent to the invisible radar site. Secondly, a predicted region is founded according to the tracking information wherein the multi-frame joint detection method is designed. Finally, target track initiation is fulfilled based on the detection results. Simulation results indicate that the presented method can achieve the performance improvement of track initiation.

Key words: distributed radar network, tracking information, multi-frame joint track initiation
