A Unique Digital Technique for Compensating for Array Element Failures

Abstract

This paper presents a review of work by H. Steyskal and R. Mailloux on a scheme to correct the pattern of an array with failed elements. The technique provides exact correction at the angles of selected received sources and minimizes the radiation at all other angles. The procedure is compatible with a digital beamformer processor. The paper highlights an analytical procedure to control the pattern in regions where there are no incident sources, thus leading to realizable solutions throughout radiating space.
