Abstract

The invention relates to a microwave communication device and method. The device comprises a first laser transmitter, a second laser transmitter, a dichroic mirror, a microwave signal receiver, a first microwave source, a second microwave source, a photoelectric detector and a demodulator. According to the invention, an electromagnetic induction transparent spectral signal generated when Rydberg atoms act with microwaves is used as a detection means, beat frequency is generated on a microwave signal receiver through a first microwave source and a second microwave source, so that the electromagnetic induction transparent spectral signal of the Rydberg atoms generates sinusoidal oscillation, and a sinusoidal oscillation signal is obtained. By detecting the to-be-modulated signal and the sinusoidal oscillation signal loaded on the second microwave, receiving of the weak carrier signal can be realized, and microwave communication is realized.

Description

technical field [0001] The invention relates to the technical field of microwave signal reception, in particular to a microwave communication device and method. Background technique [0002] Microwave communication has become the main means of communication in daily life, military activities, aerospace and other fields. Traditional microwave communication is based on the reception of microwave signals by dipole antennas. However, the traditional microwave communication method is limited by the detection sensitivity. The minimum detectable microwave intensity is about 1mV / cm, which makes it difficult to receive extremely weak carrier signals, making it difficult to achieve ultra-long-distance transmission. Moreover, the traditional microwave communication method needs to use different receiving antennas to receive carrier signals of different frequency bands, which increases operational complexity and increases industrial production costs. Contents of the invention [000...
