Abstract:

By analyzing the principle of dual plane cooperative passive location based on direction-finding cross localization, the error model is established, and factors affecting the position error are introduced.Computer simulation on the error of double collaborative passive location from three factors is conducted,including baseline in dual plane location, the distance and the azimuth 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 are given
