摘要：
We report the development and demonstration of the first true time-delay (TTD) fiber-optic beamformer for ultrawide-band antenna receive operation, The beamformer is based on a dispersive-fiber prism configuration that properly time delays the signals originating at each receiving element for coherent combining in the microwave domain, The time-steered receive antenna consists of eight spiral elements arranged into a one-dimensional (1-D) sparsely populated array, The receive array shows an instantaneous bandwidth of 6-18 GHz, limited by the available matched microwave amplifiers, The array performance is measured in an anechoic chamber and exhibits unprecedented squint-free steering over an azimuth scan of 120 degrees over the full frequency range.
