1. A method for tracking a signal origin using a spectrum analysis and management device, comprising:
- determining a Time Difference of Arrival for a signal of interest;
determining a Frequency Difference of Arrival for the signal of interest;
identifying a location from which the signal of interest is transmitted;
determining that at least four known emitters are present at the identified location;
collecting and measuring a Received Signal Strength (RSS) of the at least four known emitters and the signal of interest;
measuring a frequency shift using the RSS;
obtaining a cross ambiguity function for the signal of interest; and
resolving a position of an emitter from which the signal of interest is emitted.

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.
