The embodiment of the invention provides a frequency sweep broadband signal generation system and a frequency sweep broadband signal generation method. The frequency sweep broadband signal generation system comprises a first laser used for generating a first laser signal, a backward Rayleigh scattering structure which is used for generating a backward Rayleigh scattering signal, a positive feedback loop structure which is used for generating an optical carrier signal and a second laser signal comprising a plurality of optical sidebands, an optical filter which is used for filtering an optical sideband included in the second laser signal to obtain a filtered second laser signal comprising an optical sideband, a first optical coupler which is used for processing the first laser signal and the filtered second laser signal to obtain a first coupled optical signal, and a first photoelectric detector which is used for performing beat frequency processing on the first coupling optical signal to obtain a target frequency sweep broadband signal.
Description
technical field [0001] The embodiments of the present disclosure relate to the technical field of microwave photonics, and more specifically, to a system for generating a frequency-sweeping broadband signal and a method for generating a frequency-sweeping broadband signal. Background technique [0002] As a new type of first coupled optical signal generator, the optoelectronic oscillator constructed by the optoelectronic hybrid resonator has the ability to generate complex signals. A typical optoelectronic oscillator system mainly includes core devices such as lasers, electro-optic modulators, delay units, optical amplifiers, photodetectors, and electrical amplifiers. These devices can form a closed positive feedback system. [0003] In the process of realizing the concept of the present disclosure, the inventors found that there are at least the following problems in the related art: it is difficult to generate a frequency-sweeping wideband random signal that can be continu...
