Paper Abstract

Two optical beam forming network (BFN) architectures that are deemed viable for on-board satellite phased-array antenna applications are assessed for functional capacity and technology feasibility: specifically, the implementation issues, reliability, and long-term performance are discussed for an M-beam, N-element phased-array antenna operating at Ka-band. Also included are the results of recently demonstrated proof-of-concept BFNs employing fiber optic true-time delay elements and coherent optical processor (COP) based approaches. The details of the trade-off study results and relevant POC hardware developed will be presented in the conference to demonstrate the advantage of light weight and large bandwidth capability of photonic beamforming which are at premium in large antenna arrays. Coherent optical processor using Fourier transform has many advantages.
