Abstract：Microwave signal frequency measurement technology has an important application in modern science and technology,which is widely used in communication,radar,navigation and sensing and other fields.At present,the microwave frequency measurement based on electronics has been very mature,but there are still drawbacks such as susceptible to electromagnetic interference,difficult to realize high fre-quency and large range measurement.Microwave photonics technology,which integrates the advantages of photonics and electronics,can effectively overcome the above problems,and has obvious advantages in high-frequency broadband micro wave signal measurement,such as large bandwidth,high frequency,and anti-electromagnetic interference.This paper introduces the main microwave photon frequency measure-ment technology of the basic principles and typical implementation of the program,a systematic review of recent years based on microwave photonics microwave frequency measurement technology research pro-gress,and finally on the major categories of frequency measurement technology advantages and disadvan-tages of a comparative analysis,and look forward to the future development of microwave photon frequen-cy measurement technology.
