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.

Измерение частоты нескольких СВЧ-сигналов в режиме реального времени на основе оптоэлектронного смешения с частотно-модулированными оптическими сигналами

В данной статье предлагается метод измерения частоты СВЧ-сигналов в режиме реального времени на основе оптоэлектронного смешения с частотно-модулированными оптическими сигналами. Изложен принцип измерения частоты СВЧ-сигналов, а также экспериментально продемонстрирована возможность одновременного измерения частоты нескольких СВЧ-сигналов с неопределенностью измерения менее 40 МГц.
