Abstract
A method utilizes signals received from the signal source by receivers during respective time intervals and data about a change in positions of the receivers during these time intervals. The method includes applying first processing to each of the signals received by each respective receiver to determine an accumulated phase in the signal during a respective time interval. Applying second processing to determine differential phases differences between the accumulated phases of the signals received by two or more pairs of the receivers. The phases differences are indicative of the difference between the changes of the distances of the respective receivers from the signal source during the respective time intervals. The method includes applying a third processing for determining the location of the signal source such that the relative changes between the positions of the respective receivers relative to the determined location correspond to the distance differences of the phase differences.
