摘　　要：紧凑型地波雷达检测目标时回波信噪比低。应用传统的先检测后跟踪方法进行目标探测时,弱目标回波容易淹没在杂波和噪声中,出现弱目标漏检和虚假点迹误检,导致跟踪时易发生航迹断裂、误跟踪等现象,影响目标跟踪的连续性。为提升紧凑型地波雷达对海上运动目标的长时跟踪能力,建立检测器与跟踪器之间的信息动态交互机制,提出一种紧凑型地波雷达目标检测跟踪一体化方法。实验结果表明,与先检测后跟踪方法相比,所提方法跟踪得到的平均航迹时长增加了17.52 min。结合工程应用需求,在Matlab R2018b环境下开发了紧凑型地波雷达目标检测跟踪一体化实验平台,为紧凑型地波雷达海上目标探测实验测试提供了平台支撑。Due to the low signal to noise ratio of target echoes for compact high-frequency surface wave radar(HFSWR),the targets with weak echoes are easily submerged into clutter and noise and difficult to be detected with missed detections and false plots produced,leading to track fragmentation and false tracking when traditional detection before tracking methods are used for target observation,which degrades the tracking performance in terms of tracking continuity.To achieve the long-term tracking of sea surface moving targets for compact HFSWR,a method of integrated target detection and tracking is proposed,and an information dynamic interaction mechanism between the detector and tracker is established.The experimental results show that the average track length obtained by the proposed method increases 17.52 minutes,compared with that of the detection before tracking method.According to the requirements of practical engineering applications,an experimental platform of integrated target detection and tracking for compact HFSWR is developed under the MATLAB R2018b,which provides a basic experimental platform for sea surface target observation using compact HFSWR.
