Abstract
A photonic true time delay system for steering one or more radio frequency beams from an electronically scanned array antenna incorporates passive optical true time delay modules for the entire array based upon dense-wavelength-division multiplexed encoding of optical time delays. In addition, electronic selection of time delays allows for elimination of optical filter tuning and optical switching, and can function in either or both transmit and receive modes of the antenna array.
