摘　　要：微波传感器现广泛应用于商业、军事、勘测等领域,而传统传感器已经无法满足现实的需求,因此需要一种新型微波传感器来实现弱场的测量。针对传统的微波偶极振子传感器灵敏度低、测量时需要校准、自带天线会影响测量、工作频段窄等问题,介绍了一种基于里德堡原子的微波传感器。这种传感器不仅能够更好地对弱场进行探测,还能传递基带信号,达到无线通信的目的。从基本的物理原理对里德堡原子微波传感器进行了详细的介绍,对掌握微波弱电场探测原理与技术基本知识以及进一步推广和应用具有重要的意义。Microwave sensors are now widely used in commercial,military,surveying and other fields.However,traditional sensors are unable to meet the actual demands and a new type of microwave sensor is needed to realize the measurement of weak fields.Traditional microwave dipole sensor has some disadvantages such as low sensitivity,calibration required during measurement,the built-in antenna perturbation effect,and the narrow working frequency band,so a Rydberg atom-based microwave sensor is introduced in this paper.This kind of sensor can not only detect the weak fields better,but also transmit baseband signals to achieve the purpose of wireless communication.Rydberg atom-based microwave sensor is introduced in detail from the basic physical principle,which is of great significance for mastering the basic knowledge of microwave weak field detection principle and technology and for further promotion and application.
