地面动目标指示(GMTI)雷达可对地表战场区域进行广域监视和海量目标连续跟踪,能够提供可靠的战场情报信息,然而实际应用时真实雷达多目标跟踪系统的随机噪声、地杂波分布等对地面动目标跟踪结果产生较大影响.针对GMTI动目标跟踪应用环境特点,采用与道路约束相结合的方法进行地面慢速目标跟踪,将道路网按地形分块索引,加速道路匹配过程,应用交互式多模型(IMM)适应地面目标发生机动情况.实验结果表明,该方法可以明显提高雷达系统跟踪性能,达到实用要求.

Ground moving target indication (GMTI) radar can perform surveillance of broad area of the ground surface battle field and continuous tracking of huge quantity of targets, and provide the reliable intelligence and information. In practical use, however, the random noise of real radar multi-target tracking system, the distribution of ground clutters and other factors would exert a great influence on tracking results of the ground surface moving target. In light of the features of application environment of GMTI moving target tracking, this paper puts forward a scheme of tracking the slow moving target on the ground using the method combined with road constrained. Where the road net is indexed in terms of blocked terrain, the match process of roads are accelerated, and the interacting multi-models (IMM) are applied to the case of ground target maneuvering. Experimental results show that this proposed method can improve the tracking performance of radar systems greatly, fulfilling the requirements for the practical use.
