PHASED-ARRAY RADIO FREQUENCY RECEIVER AND METHODS OF OPERATION

Abstract: an rf receiver may include antenna elements to receive rf signals, and electro-optic modulators to generate corresponding upconverted optical signals by mixing an rf signal with an optical carrier beam. the rf receiver may include a transmission array having a first bundle of optical waveguides that receive and transmit upconverted optical signals from their ends. the ends may be arranged in a first pattern. the rf receiver may include an interference space to receive the upconverted optical signals to form a composite beam, and an array of single mode optical fibers that have lenses positioned in a detection plane to receive a portion of the composite beam. the first pattern of the ends generates an rf emitter interference pattern at the detection plane, and the single mode optical fiber lenses have a geometric arrangement that corresponds to the first rf emitter interference pattern.
