摘要：
A two-dimensional(2D)optical true-time delay(TTD)beam-forming system using a compact fiber grating prism(FGP)for a planar phased array antenna(PAA)is proposed.The optical beam-forming system mainly consists of a TTD unit based on the same compact FGP,one tunable laser for elevation beam steering,and a controlled wavelength converter for azimuth beam steering.A planar PAA using such2D optical TTD unit has advantages such as compactness,low bandwidth requirement for tunable laser sources,and potential for large-scale system implementations.The proof-of-concept experiment results demonstrate the feasibility of the proposed scheme.
