LOCATION ESTIMATING METHOD OF MULTIPLE JAMMERS BASED ON A TDOA METHOD

摘要

PURPOSE: A positioning tracking method of multiple jammers based on a TDOA Method is provided to accurately detect each jammer location even in case of multiple jammers.;CONSTITUTION: Multiple sensors receiving GPS signals are arranged and set as reference sensors in order to calculate TDOA. (S100) The estimates of multiple jammer locations are produced based on TDOA. (S200) The multiple estimates of location are displayed on the coordinate set up based on the sensors. (S300) When search cells and search ranges are determined, by moving as a searching interval, the search cell including all true position solutions as many as the number of sensors is searched out.(S400) The number of jammers is determined and the position solutions of jammers are calculated(S500).;COPYRIGHT KIPO 2013;[Reference numerals] (S100) Step of calculating a TDOA measured value; (S200) Step of calculating a position value; (S300) Step of displaying a position value; (S400) Step of setting a searching range and of searching a searching cell; (S500) Step of estimating a position
