Abstract: Recent development of high-power microwave measurement and calibration have been given in this paper. Detailed introductions also show for typical measurement methods as well as their merits and drawbacks. New method named cascade couplers technique for the measurement of high-power microwave has been proposed which has the merits of accuracy, reliability, traceability, real-time and multiparameters measurement.

Key words: High-power microwave, Power measurement, Calibration
