基于区间数及DS证据理论的多传感器航迹关联方法
A Multi-sensor Track Association Method Based on Interval Number and DS Evidence Theory
摘要
针对多传感器航迹关联问题, 提出了一种基于区间数和DS(Dempster/Shafer)证据理论的解决方法。该方法通过分析误差对参数测量的影响, 构建传感器探测目标参数真实值区间数, 通过计算区间数之间的相对支持度, 获取目标参数对于航迹相关的支持程度, 基于DS证据理论将不同参数对航迹相关的支持程度进行合成, 以此解决航迹关联问题。实例表明, 该方法能够较好地解决多传感器航迹关联问题。
Abstract
A method for multi-sensor track association based on interval number and DS evidence theory is presented.Through analyzing the influence of error on parameter measurement, the interval numbers of target parameter true value detected by the sensors are established.The relative support level between the interval numbers is calculated, based on which the support level of track association about target parameter is obtained.Then, the support levels about track association of different parameters are combined based on DS evidence theory, and thus the problem of track association is solved.Examples show that this method is effective for multi-sensor track association.
