双站紧凑型地波雷达海上目标航迹融合探测

Marine Target Track Association and Fusion Method for Dual-station Compact HFSWR

多站地波雷达的融合探测,可以扩展探测区域,提高地波雷达海上目标的跟踪性能和定位精度。基于检测级点迹关联主要适合于大型阵列式地波雷达,并不适合于紧凑型地波雷达。因此,针对双站紧凑型目标航迹关联和融合方法进行研究,发展了基于序贯相似度的双站紧凑型地波雷达目标航迹最优化关联方法。通过基于AIS信息地波雷达模拟航迹的仿真分析,表明:基于航迹信息的双站地波雷达目标关联概率明显高于基于点迹信息的关联结果,且双站融合结果误差较融合前明显降低。最后,基于实测双站紧凑型地波雷达目标探测数据,验证了本文方法的有效性。

Fusion results of multi-station high frequency surface wave radar(HFSWR) can extend the detection area, and improve the tracking performance and positioning accuracy. The detection-level point correlation is mainly suitable for large-array HFSWR, while it is not suitable for compact HFSWR. In this paper, the research on the dual-station compact target track association and fusion method is carried out, and the target track association optimization method of the dual-station compact HSWSR based on sequential similarity is developed. Based on the analysis of simulated target tracks from AIS information, the results show that the association probability of the two-station HFSWR based on the track information is significantly higher than that of based on the point information, and the measurement error of the fusion result is also lower than that of tracks before the fusion. Finally, the proposed target track association and fusion method is verified based on the measured target data.
