Photon-assisted microwave signal copying method and device

The invention discloses a photon-assisted microwave signal copying method. A signal copying method based on the photon technology is utilized, microwave signals are converted to an optical domain through electro-optical conversion, the advantages of parallel processing, accurate delay control, low transmission loss and the like of the photon technology are utilized, and the problem that non-cooperative signals with uncertain frequency and bandwidth are difficult to copy through a traditional electronic system copying method is solved; according to the invention, a method of time domain signal cutting and signal parallel copying is utilized to cut a long-time-width signal into a plurality of short-time-width signals which are connected in parallel, and then the short-time-width signals are copied in parallel by utilizing the parallel signal copying modules. The problem that a traditional signal copying method based on the photon technology is difficult to copy signals with uncertain starting time and duration
