Abstract: Aiming at the inherent defects of traditional high power microwave testing methods,a high power microwave testing method based on microwave photonics is introduced.Based on this method,an optoelectronic high power microwave test system is designed.This test system has the advantages of low disturbance,large instantaneous dynamic range,strong anti-interference ability,and can simultaneously collect the characteristics of high power microwave time/frequency domain signals.The system is tested and verified with high power microwave pulse signal,and the measured data completely shows the signal characteristics of high microwave pulse in time/frequency domain,which verifies the feasibility and effectiveness of the test system and method.

Key words: High power microwave, Microwave photonics, Photoelectric high power microwave testing system
