摘　　要：微波信号的频率测量在航空航天等领域中具有广泛的应用需求。传统的基于纯电子学手段的频率测量方案频率范围和带宽受限,难以实现对高频率、大带宽信号的测量。微波光子技术能够结合光子技术和微波技术的各自优势,具有大带宽、高载频、低损耗、抗电磁干扰和高分析精度等特点,可实现高性能的微波信号频率测量。系统性地综述了基于频率-时间映射机理的微波光子频率测量技术,介绍了频率-时间映射的基本原理,并对基于色散介质和不同种类扫频组件的频率-时间映射方案进行了详细介绍,最后对该领域的发展进行了总结和展望。Frequency measurement of microwave signals has a wide range of applications in the fileds such as aero⁃space and electronic system.The traditional frequency measurement scheme based on the electronic method has lim⁃ited frequency range and bandwidth,making it difficult to measure the signals with high frequency and large band⁃width.The microwave photonic technology can combine the advantages of optical and microwave technologies in terms of large bandwidth,high center frequency,low loss,anti-electromagnetic interference as well as high accuracy,and can achieve microwave frequency measurement with good performance.This article reviews the microwave pho⁃tonic frequency measurement methods based on frequency-to-time mapping.The basic principles are provided,and detailed introduction to the frequency-to-time mapping schemes based on dispersive media and different types of scan⁃ning components are given.Finally,a discussion of the future development is provided.
