Demonstration of an RF-Photonic Microwave Channelizer Using an Optical Fiber Recirculating Loop

摘要

A new type of RF-photonic channelizer is demonstrated which makes use of a pulse replication loop to realize a true time domain correlation receiver. We have demonstrated, for the first time, a one-step channelization of a total bandwidth of 1.3 GHz and over 400 channels from a single input RF signal pulse. Our channelizer's system architecture is scalable and tunable to a total bandwidth of tens of GHz and over a thousand channels.
