Abstract

A new architecture for optically controlled phased array antenna, providing true time delays, is described. Heterodyne generation of the microwave signal is analyzed, especially with regard to spectral bandwidth and signal to noise ratio. Some of the requirements of optoelectronic devices implemented in the architecture (laser, spatial light modulators, detectors,...) are discussed. Experimental set up and results are presented.
