Ship target tracking for marine radar in occluded environments
In order to address track breakages that commonly occur in occluded environments for marine radar target tracking with an unmanned surface vehicle (USV), it is necessary to comprehensively utilize prior environmental information to improve track continuity when radar detection is occluded.
An occluded integrated probability data association (IPDA) algorithm, known as O-IPDA, is proposed for the real-time prediction of environmental occlusion information. Appropriate use is then made of its low detection probability in combination with a tailored track existence probability transition matrix to maintain target tracking performance.
For the application of single target tracking, O-IPDA can avoid target track loss in temporarily occluded environments where its track maintenance ability during occlusion is determined by the corresponding parameters in the existence state transition probability matrix.
The proposed O-IPDA algorithm has the potential to address target occlusion in complex maritime environments and can provide useful references for marine radar single target tracking.
针对无人艇平台航海雷达在舰船目标跟踪中因障碍物遮挡而造成的目标航迹断裂问题，需综合利用环境先验信息，以提高雷达探测受限时目标跟踪航迹的连续性。
通过提出遮挡环境下的综合概率数据互联（IPDA）算法，即O-IPDA，对环境遮挡情况进行实时预判；在遮挡环境中通过采用低检测概率和针对性设计的存在状态概率转移矩阵，以维持目标跟踪的连续性。
在单目标跟踪场景中，当目标被暂时遮挡时，O-IPDA可以避免目标因持续性漏检而丢失，以保持跟踪航迹的稳定性，其中算法的抗遮挡能力取决于O-IPDA存在状态概率转移矩阵中的相关参数设置。
O-IPDA目标跟踪方法具有一定的抗遮挡能力，可为航海雷达单目标跟踪研究提供参考。
