An optical time delay network (OTDN) for time delay steering of phased arrays of various sizes is projected. The approach involves integrated optic switches and sections of optical waveguide for time delays. An example phased array radar is defined. The impact of time delay network performance parameters such as insertion loss, network switch isolation and triple transit effects on radar system performance such as noise figure, dynamic range, phase and amplitude linearity and sidelobe levels is analyzed. Performance levels needed within the optical time delay network to meet projected radar system requirements are identified.
