Research on Flight Test Method of Dual Plane Cooperative Passive Localization

By analyzing the principle of dual cooperative passive location based on direction-finding cross localization in this paper, the error model is established,and factors affecting the position error is introduced. conducted computer simulation on the error of double collaborative passive location from three factors,including baseline in dual location, the distance and the bearing of target plane.Through designing the flight profile based on positioning accuracy requirements ,two typical flight routes of dual cooperative passive location are proposed,and the methods of evaluation and processing on test results is given.
