Abstract
In order to improve the localization accuracy of passive reconnaissance systems,this paper makes a study on joint localization combining direction-finding cross and three-station time difference.Based on the mathematical models of direction-finding cross and three-station time difference localization,first is derived the mathematical model for joint localization integrating direction-finding cross and time difference,and are analyzed the factors affecting its localization error.Then,the geometric dilution of theoretical localization accuracy is pro-vided,and finally,simulation experiments are conducted.The simulation results verify the factors affecting the joint localization accuracy of direction-finding cross and time difference,which has guiding significance for the design in practical engineering applications.关键词
