Abstract:
Methods for tracking a signal origin by a spectrum analysis and management device are disclosed. Signal characteristics of other known emitters are used for obtaining a position of an emitter of a signal of interest. In one embodiment, frequency difference of arrival technique is implemented. In another embodiment, time difference of arrival technique is implemented.

Claim (Index 9):
A method for tracking a signal origin using a spectrum analysis and management device, comprising:\n determining a Time Difference of Arrival or a Frequency Difference of Arrival for a signal of interest; identifying a location from which the signal of interest is transmitted based on coordinates provided from a Global Positioning System (GPS) receiver; determining whether at least four known emitters are present at the location; obtaining a cross ambiguity function for the signal of interest; determining the cross ambiguity function converges to a solution; aggregating frequency shift data; applying one or more filters to the aggregated frequency shift data; and resolving a position of an emitter from which the signal of interest is emitted.
