Abstract

The use of optical fibres as delay lines configured to act as a beamformer for a phased array is described. Such a beamformer operates at intermediate frequency or low microwave frequency. The relationship between operating frequency and phase accuracy in the beam-former is discussed. A detailed expression for critical system parameters of the beam-former is derived and verified with a simple experimental model operating at 120 MHz. The construction of the nodes in the beamforming network is identified as a critical feature in design on which effort needs to be concentrated.
