Provided is a radio source position estimation system including a plurality of radio transmission devices spaced a predetermined distance apart from one another and configured to transmit radio frequency (RF) signals received from an arbitrary radio source and a central radio reception device configured to estimate a position of the radio source using the RF signals received from at least three radio transmission devices.

Radio source position estimation system

Disclosed is a localization method of multiple based on a TDOA method, including calculating TDOA measurements step Sof arranging multiple sensors, and calculating TDOA measurement values while a reference sensor is changed, in turn; locating multiple jammers using all TDOA measurements step Sof calculating estimated location solutions of the multiple jammers; a finding a searching quadrant step Sof finding a quadrant having the highest density of the estimated location solutions; a setting a searching range and detecting searching cell step Sof deciding a searching range, and searching the searching cell; and determining estimated positions of the multiple jammers step Sof deciding the number of the jammers, and calculating location solutions of the multiple jammers. Therefore, the present invention can accurately localize the multiple jammers.
