Estimation of the direction of arrival based on the three-channel Rydberg atomic receiver

In recent years, the application of Rydberg atomic receivers in wireless communication and perception has attracted extensive interest due to the precise response of Rydberg atoms to radio-frequency fields. To explore the estimation performance of atomic receivers in the direction of incoming waves, a novel three-baseline direction-finding algorithm based on the Rydberg atomic direction-finding receiver is proposed to realize the estimation of the incoming wave direction of 3.5GHz RF signals from different orientations. The simulation results demonstrate that the three-channel direction finding algorithm proposed in this paper has excellent omnidirectional direction estimation performance for estimating the incoming wave direction of a single sigal in two-dimensional space.
