Abstract

In this paper, the optical method of instantaneous microwave frequency measurement based on fiber Bragg gratings with high chromatic dispersion is proposed. The mathematical model of the microwave photonic device realizing this method is developed. The possibility of measuring the microwave signal frequency by this method in a wide range from 3 to 40 GHz with an uncertainty of less than 100 MHz is shown.

В данной статье исследуется оптический метод измерения частоты СВЧ-сигнала в режиме реального времени на основе волоконных брэгговских решеток с высокой хроматической дисперсией. Построена математическая модель радиофотонного устройства, реализующего данный метод. Показана возможность измерения частоты СВЧ-сигнала данным методом в широком диапазоне от 3 до 40 ГГц с неопределенностью менее 100 МГц.
