Abstract:

Frequency measurement of microwave signals has a wide range of applications in the fileds such as aerospace and electronic system. The traditional frequency measurement scheme based on the electronic method has limited frequency range and bandwidth, making it difficult to measure the signals with high frequency and large bandwidth. 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 photonic 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 scanning components are given. Finally, a discussion of the future development is provided.

Key words: photoelectric measurement, ?microwave signal frequency measurement, ?microwave photonics, frequency-to-time mapping, ?optical and electronic signal processing
