摘　　要：工作在扫描方式下的分布式雷达面临多站数据的目标轨迹匹配问题,难以有效进行多站分布式积累。文中提出一种基于序贯贝叶斯的多站融合算法,该方法可以完成多站雷达不同扫描帧间的多目标轨迹关联匹配,从而有效实现多站信号级融合并获取分集得益。并以该方法为基础,设计面向工程化应用的扫描方式下分布式雷达多站融合解决方案。基于外场试验平台实录数据进行仿真验证,处理结果表明了该方法的有效性。Distributed radar working in scanning-mode is faced with the problem of target＇s trajectory matching,so it＇s difficult to accumulate multi-station＇s signal effectively. We propose a novel multi-station fusion method based on sequential Bayesian algorithm that can associate multi-station＇s data from different scanning-frames,and further more realize multi-station signal fusion to achieve space diversity gain. A solution based on the method is designed for the engineering application of distributed radar under scanning work mode. Experimental results with measured data indicate that the proposed method is effective.
