摘　　要：提出了一种基于信息融合的目标管理与被动定位技术的总体思路与实现方法。以坦克分队对目标的管理和被动定位需求为应用背景,首先利用战场图像信息提取目标种类、位置和姿态特征,并依次通过对目标3类特征的对比判定,解决了被动定位前对不同坦克瞄准镜视场中目标是否为同一目标的判定问题,实现了对敌方目标的全局统一编号与动态管理;其次利用坦克自身位置和测得的目标方位、俯仰等角度信息,推导了目标位置坐标的计算公式,分析了计算误差的主要影响因素;最后利用坦克分队网络化协同作战的优势,提出了一种以目标位置估计误差最小为约束条件的目标被动定位系统误差融合估计与补偿算法,显著提高了目标被动定位的精度,并通过仿真和野外实验,验证了所提方法的有效性。A method for target management and passive target location based on information fusion is put forward.The target management and passive location demand of tank unit are taken as the application background.Firstly,the image information of the battlefield is used to acquire the type,position and pose information of the target,and the problems of how to determine the identity of the same target in different tanks＇ telescopes and the management of the target are solved through the comparison of the three kinds of characteristics of the target.Then the target position estimation is achieved by using our tank location and the vertical angle,horizontal angle of the target,and the main sources of error are analyzed.Finally,an algorithm of error fusion estimation and compensation for the passive target location system is proposed based on minimizing the error of target position estimation.The precision of passive target location is enhanced evidently,and the validity of the method is verified by simulation and field experiments.
