Systems, methods, and devices for electronic spectrum management

摘要

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.

主权项

1. A method for tracking a signal origin using a spectrum analysis and management device, comprising the steps of:
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 less than four known emitters are present at the location; measuring an angle of arrival for the single of interest and the less than four known emitters; measuring a frequency shift for the signal of interest; obtaining a cross ambiguity function for the signal of interest; resolving a position of an emitter from which the signal is emitted; and displaying the position of the emitter of the signal of interest.
