摘要
Abstract
The Rydberg atomic antenna has gradually shown great application prospects due to its inherent advantages such as high precision,ultra wideband signal reception ability,and self value traceability.This paper mainly discusses the influence of refer-ence field intensity on the measurement results under superheterodyne.We found only when a small target signal is applied,there is a good linear relationship between target signal and mixing signal,which is not related to the strength of reference field,and large target signal can lead to system entering the nonlinear region.Meanwhile,we determine both the reference field strength and the mixing frequencies will affect the system's ability to detect external microwave fields,we found that as the reference signal gradually increases,the system's measurement capability exhibits an increasing and then decreasing trend(The optimal value of this paper is around PL＝0 dBm),and for the mixing frequency,the system's measurement capability diminishes as it continues to in-crease.Besides,we analyzed the logarithmic relationship between the target signal and the A-T splitting distance of the EIT,and verified it through experiments.关键词
