Abstract
AbstractThis presentation1 reviews the Georgia Tech Research Institute’s (GTRI) contributions to the field of nonlinear oscillator antennas. Over the last seven years, GTRI, in collaboration with SPAWAR Systems Center in San Diego, has advanced the state of the art in the analysis, capability and design of coupled oscillator arrays. A theoretical framework describing the dynamics of coupled oscillators and its relevance to beam steering, beam shaping, monopulse and null steering is presented. Descriptions of 1- and 2-dimensional array designs are provided, including critical design issues encountered during their development. Performance assessments via range chamber testing and on-board diagnostic measurements are included. This paper concludes with a brief discussion of outstanding problems, directions of further study and possible insertion points for this technology.KeywordsLinear Stability AnalysisVoltage Control OscillatorBeam SteeringArray FactorCoupling LineThese keywords were added by machine and not by the authors.
