Abstract

The thesis examines the feasibility of using optics for signal distribution and beamforming in phased array antennas. The requirements for signal distribution in phased array antennas are identified. A computer model is developed to evaluate the performance of analogue optoelectronic distribution systems. Using this model, various optical distribution techniques which can be used in phased arrays are examined, with particular reference to a satellite-based application. A model for semiconductor laser amplifiers with intensity modulated inputs is presented, and the optimum use of amplifiers for signal distribution is considered. Finally the feasibility of using optical techniques to perform other tasks such as beamforming is examined, and a novel opto-electronic beamformer is experimentally demonstrated. Results show that optics offer an excellent alternative to microwave techniques for signal distribution and beamforming.
