摘要: A Doppler shift measurement system based on four-wave mixing effect in a highly nonlinear fiber is demonstrated practically. The exhibits two low-frequency voltages, which are functions of the shift, and therefore, low-cost photodetectors can be employed system. No sophisticated electrical instrument required to perform measurement. scheme able simultaneously independently measure frequency radar echo its power level with carrier up 40 GHz. suitable any microwave photonics (MWP) broad agility characteristics or other MWP systems operating hopping technique.
