摘要: 借鉴多维分配的思想,把整体相关和最近邻方法相结合,将多个传感器情况下的被动数据关联问题进行降维处理,并利用χ2分布进行统计检验,以判断不同传感器测量数据的关联组合是否是来自同一个目标的正确组合,最终实现有效排除测向交叉定位中虚假定位点和准确定位的目的,实现多传感器多目标无源被动跟踪.仿真结果表明,利用文中的方法无源传感器可较好地对多目标进行定位,而且计算量适中.

Abstract: A new method is studied to associate the bearing measurements of different passive sensors.This method uses multidimension assignment algorithm for reference.The nearest-neighbor method is combined with the holistic correlation method to reduce the dimension of bearing measurements association,and a chi-square test is used to select the correct bearing measurements association.This method can eliminate the ghosts created by direction finding line of multiple passive sensors.Simulation results show that using the proposed method,the passive sensors can locate multiple targets simultaneously,and the computation burden is moderate.
