RF Photonics for Array Processing MURI 5th Year Summary
Abstract
This report covers the fifth year of progress of the 1997 MURI on RF Photonics for Antenna Arrays at the University of Colorado, Montana State University, George Mason University, and the University of California Davis. Novel techniques for optical control and processing of the wideband RF and microwave signals encountered in phased array antennas have been developed, guided by research in spatio-temporal adaptive processing algorithms and active quasioptical RF antenna arrays. The primary goal of this research is to develop enabling optical techniques that provide dramatic improvements in antenna array performance over conventional RF, optical, and digital techniques, allowing the efficient processing of large broadband antenna arrays. Coherent modulation and detection is made robust and practical by the use of dynamic holography in photorefractive and optical coherent transient media. This report summarizes the teams management, educational, and outreach activities, as well as technical progress in the fifth year on the constituent projects - broadband adaptive optical array processing, spatio-temporal array-processing algorithms, coherent-transient true-time-delay, photoreflactive signal extraction, optical antenna control, and polymer in-line fiber modulators.
