| Abstract: | Rydberg atom is an atom in a high-energy state with a large leap dipole moment. Measurement and reception of electromagnetic fields in the microwave band can be achieved by using the electromagnetic induction transparency and the Autler-Townes splitting effect. In recent years, Rydberg atom-based radio technology has emerged in the field of communications, radar and other electronic information systems. Atomic receiver can demodulate amplitude modulated signals and FM signals, and it also has the ability to measure pulse signal and phase information. This paper mainly reviews the research of radio technology based on Rydberg atom, introduces the basic principle and research progress of atomic receivers in detail, and briefly discusses its future development. |
