Abstract
An adaptive detection and nulling system includes an antenna or radio frequency aperture, an electronically tunable radome placed over the antenna or radio frequency aperture, the radome including a plurality of scatterers on a substrate, and one or more tunable reactance elements connecting at least two of the scatterers, a microcontroller coupled to the tunable reactive elements and configured to control the reactance values of the one or more tunable reactance elements, and a sensing circuit coupled to the microcontroller, wherein inputs from the sensing circuit are used by the microcontroller to adaptively determine bias voltages to the one or more tunable reactance elements using characterization data of the radome to control the tunable reactance elements to form one or more nulls in a receive radiation pattern of the antenna.
