Abstract
An approach to broadband beamforming for receiving microwave antenna arrays based on photonic true time delays (TTD) is considered. Many architectures have been proposed earlier for the implementation of TTD with fiber optic components usage to provide control of one- or multibeam antenna array pattern. Some beamforming arrangements can currently provide the required TTD capabilities by using the units and elements available at the market of modern components of fiber-optical telecommunication systems. The essential parameters of accessible analog fiber optic link main components are considered. The technique is developed and calculations of the main performance data of the chosen beamforming scheme – the signal/noise ratio and dynamic range are carried out. Influence of the scheme components’ parameters and their operation modes on the estimates of the beamforming scheme main performance characteristics is analysed.
