Abstract:Due to the limitation of the measurement accuracy of classical radio signals, the time comparison accuracy can only reach ns level. In this paper, a time comparison scheme of Beidou system based on microwave-optical entangled signal is proposed, which effectively combines the long-distance transmission advantage of microwave signal with the single photon detection advantage of optical signal by electro-opto-mechanical converter, and the phase difference is solved by a phase conjugate processor ,so as to calcul… Show more
