摘要： PURPOSE: A position measuring method of an unknown signal source based on TDOA(time difference of arrival) is provided to reduce influence of a sampling cycle, thereby accurately finding the position of the unknown signal source. CONSTITUTION: A position measuring method of an unknown signal source based on TDOA comprises the following steps: An unknown signal is received from multiple sensors (S100). A cross correlation on the discrete delay time is performed for the obtained signal, the value of cross correlation is obtained, and the value of target function is calculated (S200). A reference sensor is chosen to produce a TDOA measured value (S300). A delay time cross correlation is performed for each received signal in the chosen sensor and another sensor, and the time when the cross correlation value is maximum is calculated (S400). The position of the unknown signal source is measured by using the TDOA measured value (S500). [Reference numerals] (S100) Step of obtaining data; (S200) Step of calculating the value of a target function; (S300) Step of selecting a reference sensor; (S400) Step of calculating a TDOA measured value; (S500) Step of measuring a position

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).
