1. A method for determining the location of a transmission source, the method comprising the steps of:
- receiving at a plurality of signal receiving locations at least one signal from a transmission source;
determining a signal magnitude of each of the at least one transmission signal received at the plurality of signal receiving locations; and
processing each of the signal magnitudes with a statistical model of the signal propagation characteristics associated with the signal space between the transmission source and each of the receiving locations to determine the location of the transmission source.

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.

14. A system for determining the location of a transmission source comprising:
-
a transmission source capable of transmitting at least one signal;
a plurality of receivers each capable of receiving the at least one transmitted signal;
a processor capable of determining signal magnitudes of the at least one transmitted signal as received by each of the plurality of receivers and capable of processing each of the signal magnitudes with a statistical model of the signal propagation characteristics associated with the signal space between the transmission source and each of the receiving locations to determine the location of the transmission source. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
