Abstract: 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.

Abstract: A disturbance signal detection apparatus may comprise; a receiver configured to receive a first signal including at least one distortion signal, a continuous wave (CW) signal detector configured to detect a CW distortion signal from the first signal based on a frequency characteristic, and a filter configured to output a second signal by filtering out the detected CW distortion signal from the first signal.

Abstract: Disclosed is a localization method of multiple based on a TDOA method, including calculating TDOA measurements step S100 of arranging multiple sensors, and calculating TDOA measurement values while a reference sensor is changed, in turn; locating multiple jammers using all TDOA measurements step S200 of calculating estimated location solutions of the multiple jammers; a finding a searching quadrant step S300 of finding a quadrant having the highest density of the estimated location solutions; a setting a searching range and detecting searching cell step S400 of deciding a searching range, and searching the searching cell; and determining estimated positions of the multiple jammers step S500 of deciding the number of the jammers, and calculating location solutions of the multiple jammers. Therefore, the present invention can accurately localize the multiple jammers.
