Abstract

We demonstrate a novel architecture enabling the correlation in real-time of broadband RF signals (> GHz). Contrary to conventional digital correlators, our technique is analog: no digitization nor digital signal processing is required. The correlation is performed in the optical domain, enabling the processing of multi GHz signals. Moreover, the proposed architecture calculates in real-time the correlation function for more than 200 values of the delay simultaneously. Applications of the technique range from radio-astronomy, to transmitter localization by Time Difference of Arrival.
