Performance of an MEG adaptive-beamformer source reconstruction technique in the presence of additive low-rank interference
TL;DR: The analysis shows that the adaptive beamformer techniques are insensitive to interference when its spatial singular vectors are so different from a lead field vector of a brain source that the generalized cosine between these two vectors is much smaller than unity.

Superresolution of Coherent Sources in Real-Beam Data
Shikhar Uttam,Nathan A. Goodman +1 more
TL;DR: This work study the unique problems associated with resolving the direction of arrival (DOA) of coherent signals separated by less than an antenna beamwidth when the data are collected in the beamspace domain with, for example, electronically or holographically scanned antennas and proposes a technique that is able to resolve these coherent signals.

Improving Sonar Performance in Shallow Water Using Adaptive Beamforming
TL;DR: In this paper, the adaptive beamforming on the receiver side was used to reduce multipath interference and hence improve the signal-to-noise ratio (SNR) of a small, dense receiver array, and the results showed that with a small vertical array, a narrow mainlobe width is more important than low sidelobe levels, in terms of maximizing the SNR.

Sound Field Analysis along a Circle and Its Applications to HRTF Interpolation
TL;DR: In this article, the Fourier domain representation of the sound field is used, and an angular sampling theorem is developed for the sampling and interpolation of a sound field in two and three dimensions along a circle.
