摘要
航迹融合由航迹相关和航迹合成组成,航迹相关是航迹融合的前提;针对先进场面运动引导控制系统(A-SGMCS)中场面监视雷达对目标的跟踪,文中研究了多场面监视雷达的多目标航迹相关问题;首先,建立分布式多场面监视雷达多目标航迹融合的总体框架,利用GPS授时和外推内插的方式进行场面监视雷达的同步,利用坐标平移实现空间对准;然后,介绍基于层次划分思想的聚类算法,再利用此方法进行多场面监视雷达多目标跟踪的航迹相关研究;最后,进行了仿真验证;仿真结果表明,文中所采用的方法对目标数确定和不确定的航迹都能够进行正确相关,有效地解决了场面监视雷达的航迹相关问题。
Tracking fusion is composed of tracking correlation and status estimation. Tracking correlation is the key of tracking fusion. To realize the Surface Movement Radar （SMR） tracking of maneuvering target in Advanced Surface Movement Guidance and Control System （A--SMGCS）, the technique of tracking correlation is studied. Firstly, the general frame of multi--SMR mutli--target tracking fusion is built. The synchronous of SMR is realized by utilizing GPS time service and extrapolation interpolation algorithm to realize time alignment. By translating coordination to realize spatial alignment. Next, the clustering algorithm based on hierarchical division is introduced. Then , the clustering algorithm is used to study the multi--SMR multi--target tracking correlation. Finally, the simulation results show the algo- rithm can make correct tracking correlation whether the number of target is certain or uncertain, and it is effective in solving the Multi--SMR tracking correlation problem.
