Abstract :
Discusses the problems jammer location and approaches to de-ghosting. If the source can be located on a second, superimposed, coordinate system by measuring the time difference of arrival (TDOA) of signals at two spaced receivers, then triangulation ghosts can be eliminated. This technique needs only two receivers, and does not require additional information, or that the emission duration be extended. For noise-like signals, the method of obtaining TDOA is by correlation at the two sites
