The Broadband RF Channelised Reception Technology Based on Microwave Photonics

High-performance RF systems must have high instantaneous detection bandwidth, high resolution, large dynamic range, detection of multiple frequencies, multiple signals and real-time processing capability. Therefore, real-time capture of wideband shortcut information is a key technology in many applications. The objective of this paper is to investigate broadband RF channelised reception techniques based on microwave photonics. The current development status and development trend of microwave-assisted wideband signal channelised reception technology is reviewed, and the basic principles are briefly described. This paper introduces the mathematical model of wideband signal channelised reception and reconfiguration, and analyses and derives its structure principle and workflow. The performance of the wideband RF signal channelisation is analysed and the coherent signal-to-noise ratio is experimentally demonstrated to have no significant impact on the overall system performance.
