Abstract. In this paper, the optical method of instantaneous microwave frequency measurement based on optoelectronic mixing with frequency-modulated optical signal is proposed. The analytical model of the microwave photonic device realizing this method is developed. The principle of measuring microwave signals frequency based on the proposed method is described, and the possibility of simultaneous measurement of multiple microwave signals frequency in the range up to 4.5 GHz with a measurement uncertainty of less than 30 MHz is experimentally demonstrated.
Key words: instantaneous microwave frequency measurement, electrooptic Mach-Zehnder modulator, time-frequency transform, microwave photonics.
