Reducing the maximum quantization scan error in dense phased arrays

Abstract

© 2017 IEEE. In previous work, the authors derived a closed-form expression from which the maximum quantization error and scan range in the visible region could be calculated for dense regular arrays. This is a continuation of the previous work in which a more advanced beamforming algorithm is investigated. It will be shown that a significant improvement on the array factor pointing accuracy is achieved. Quantization errors however still manifests itself in the form of side lobe errors and a subsequent loss in power within the main lobe is observed. A study is performed to determine its extent.
