Design Method of Multi-Channel Multi-Function Broad-Band Reconfigurable Microwave Photon Radar

Multi-channel multi-function broad band reconfigurable microwave photonics radar has the performance advantages of multi-band, multi-function, large instantaneous bandwidth, reconfigurable, low phase noise, arbitrary frequency carrier, high-resolution imaging and so on. It is expected to realize the replacement of one radar for any function radar in any band and the reduction of the number of radars that can replace multiple radars with only one radar. It can turn multiple radars into one radar and is an important part of future radar. This paper first analyzes the needs of the future multi-functional radar, then introduces the unique performance advantages of the microwave photon multi-functional broadband reconfigurable radar, then proposes a design of the microwave photon multi-functional broadband reconfigurable radar, and introduces the system module design method to ensure low phase noise, multi band, system coherence and large instantaneous bandwidth. Finally, the performance advantages and prospects of this design are summarized.
