A Photonics-based Broadband RF Spectrum Analysis and Geolocation System

Testing of a broadband photonics-based spectrum analyzer and coherent correlator for RF emitter geolocation using time-difference of arrival is presented. Emitters including frequency hoppers and spread spectrum signals with bandwidths from 10-500 MHz covering 12-22 GHz band were located with a typi...

Description
Summary:	Testing of a broadband photonics-based spectrum analyzer and coherent correlator for RF emitter geolocation using time-difference of arrival is presented. Emitters including frequency hoppers and spread spectrum signals with bandwidths from 10-500 MHz covering 12-22 GHz band were located with a typical <; 1 ft 2 precision.
