Abstract
A radio frequency signal generation device may include an optical comb generator configured to generate an optical comb signal including a plurality of first wavelength signals having different wavelengths; a pulse shaper configured to attenuate remaining wavelength signals excluding a plurality of second wavelength signals among the plurality of first wavelength signals; an optical-electronic converter configured to generate a radio frequency signal including a carrier frequency signal from the plurality of second wavelength signals outputted from the pulse shaper; and a pulse shaping controller configured to control the pulse shaper such that a carrier frequency of the carrier frequency signal varies according to a frequency hopping pattern.
