Abstract

A system and method for determining the location of a transmission source by processing the magnitude of the transmitted signal received at a plurality of receivers with a statistical model of the signal propagation characteristics associated with the signal space between the source and each of the receivers. The system and method also are capable of determining a route of travel between the transmission source and a receiver and/or alternate location.
