Paper Abstract

A novel technique for instantaneous frequency measurement of unknown microwave signal based on both phase modulation and intensity modulation is theoretically and experimentally demonstrated. Based on the output microwave power through dispersive fiber links, three amplitude comparison functions (ACFs) are established, which are combined to measure the frequency of input microwave signal with improved measurable range and accuracy. In the frequency estimation process, the measured calibration ACFs are utilized as the look-up table. The experiment results show that measurement error smaller than 200 MHz can be obtained for the frequency from 0.5 GHz to 20 GHz.
