Abstract

This paper introduces an adaptive broadband beamforming structure which permits constant resolution over a larger frequency interval spanning several octaves. Beamformers operating in uniform subbands are grouped into units within an octave. Different octave units are applied to process signals collected from arrays of appropriately scaled aperture, therefore giving a constant overall resolution. Simulation results benefits in terms of mean square error performance and cost compared to standard uniformly and non-uniformly spaced arrays.
