Abstract:

The scope of this program was to study the application of optical techniques to signal distribution and beamforming networks in phased array antennas for Army mobile tactical communications systems, with the aim of identifying advantagous system architectures. This study included systems operating at 9 GHz original frequency for the Radio Access Point, 2044 GHz for SATCOM applications and 55 GHz for vehicle-to-vehicle line-of -sight. As a result of this study experimental optical modules were designed, fabricated and delivered. The optical modules were designed to achieve the basic functions of an optical beamforming system for the Radio Access Point. The four modules included a quadrature phase shift keying QPSK coder with optical splitterbeamformer, optical single sideband modulatorbeamformer and optical multi-input receiver.
