Paper Abstract

A new microwave photonic approach to microwave frequency measurement with a high resolution and a large bandwidth is proposed. In this method, three photonic sampling analog-to-digital converters (ADCs) with co-prime sampling rates are employed. Three Fourier frequencies acquiring through down-converted analog-to-digital conversion of the unknown microwave signal are utilized to recovery the frequency of the unknown signal. The simulation results show that a microwave frequency measurement system which is feasible for multi-frequency microwave signal achieves a large measurement range of 0-50GHz and an accuracy of±1MHz. In addition, the spur-free dynamic range of 101.1dB-Hz2/3@50GHz is also numerically demonstrated.
