Embodiment Construction
[0024] In order to facilitate those skilled in the art to better understand the improvement of the present invention relative to the prior art, the present invention will be further described below in conjunction with the accompanying drawings. The invention is described by way of illustration rather than specific limitation of the invention.
[0025] The implementation process of the microwave broadband signal processing method involved in the present invention is shown in figure 1 As shown, it specifically includes 1. Spectral slicing 2. Carrier extraction and demultiplexing 3. Envelope detection three parts, specifically:
[0026] First, "spectral slicing" is performed on the microwave broadband signal based on the photoelectric hybrid loop, including two parts: "electro-optical intensity modulation" and "circular slicing". "Electro-optical intensity modulation" aims to convert microwave signals into optical signals through intensity modulation based on electro-optical int...
