  • Method for low sidelobe operation of a phased array antenna having failed antenna elements
    Patent number: 8354960
    Abstract: Described is a method of modifying an antenna pattern for a phased array antenna having at least one failed antenna element. A number of proximate beamformers in a proximate angular region about a beamformer at an angle of interest are determined. Each of the proximate beamformers has a proximate beamformer weight vector. A corrected beamformer weight vector is determined for the angle of interest as a linear combination of the proximate beamformer weight vectors. Each element of the corrected beamformer weight vector that corresponds to one of the failed antenna elements has a value of zero. The method enables computation of low spatial sidelobe antenna patterns without requiring a recalibration of the antenna thereby enabling uninterrupted operation of systems that employ phased array antennas. The method can also be used to control taper loss or sidelobe level for phased array antennas that have no failed antenna elements.
