RF Photonics for Beamforming and Array Applications

Abstract

This lecture focuses on the applications of RF photonics for array antennas in signal distribution, beamforming, beam control, and antenna remoting. Examples are given to discuss the requirements, benefits, and design approaches of photonics for phased array antennas. The first demonstration of using photonics for a dual band array was conducted in 1990. Later a wide band conformal array controlled by photonics was built and tested. This example talks about the optical control of phased arrays by using fiber-optic links for RF and data remoting and a time-shifi beamforming network for wide instantaneous bandwidth. Last, the talk will illustrate how photonics can be used to form a wide band feed system for multibeam arrays.
