Optical beam forming techniques for phased array antennas

Abstract

Following an outline of established optical techniques for the generation and distribution of reference and control signals for phased array antennas, two novel approaches are put forward: (i) a ‘nondispersive prism’, controlling agile single beams or monopulse patterns, and (ii) a ‘lens fed model array’, which can control multiple, independent antenna beams. The prospects of fibre-optic transmission for other functions in the array are also considered.
