Webbeampattern matching design criterion, we consider a new design criterion for sensing, which aims to max-imize the minimum weighted beampattern gain at the sensing angles of interest. Accordingly, by considering each type of communication receivers, we formulate two ISAC design problems, with the conventional objective of WebApr 1, 2024 · The differential microphone array, or differential beamformer, has attracted much attention for its frequency-invariant beampattern, high directivity factor and compact size. In this work, the design of differential beamformers with small inter-element spacing planar microphone arrays is concerned. In order to exactly control the main lobe …

WebApr 8, 2015 · Subtracting beampatterns obtained for the different lancet rotations studied from the beampatterns obtained for the upright lancet showed numerous local changes (see Fig. 7) with changes in beampattern gain around 10 dB not being uncommon. The prevalence of such large gain changes increased with increasing rotation of the lancet … WebA lower bound for the maximum beampattern gain is provided through theoretical analysis, which reveals the potential performance enhancement gain that is obtained by densely deploying several elements in a metamaterial antenna. Simulation results substantiate the theoretical analysis and show that the maximum beamforming gain of a metamaterial ... truth and reconciliation day manitoba
