摘要

A frequency-hopping signal measurement scheme based on real-time photonic Fourier transform is proposed and demonstrated. Through optical frequency-to-time mapping, real-time spectrum analysis of wideband high-speed frequency-hopping signal can be achieved without additional digital signal processing. In the experiment, the wideband and multiple frequency-hopping signals with 100-ns frequency-hopping period and 4–40 GHz frequency range are verified, respectively.
