A system and method for locating a signal source are disclosed. The method utilizes signals S n received during respective time intervals {”t n } from the signal source by a number n of receivers {Rc n }, and data about the change {”R n } of the receivers' positions {R n }. The method includes processing the signals S n from each of the receivers to determine the phase ”¸ n accumulated in the signal S n during a respective time interval ”t n . Based on the determined accumulated phases {”¸ n }, the accumulated phases differences ””¸ mn (differential phase) between the signals, S m and S n , that are received by two or more pairs {m,n} of the receivers are determined. Then, the location of the signal source is determined such that it satisfies that the changes in the positions of the respective {n,m} receivers relative to that location correspond to the differential phases ””¸ nm between the signals received by the respective receivers. |
