Abstract
In various application areas, e.g., seismology, astronomy and geodesy,arrays of sensors are used to characterize incoming wavefields due todistant sources. Beamforming is a general term for phased-adjustedsummations over the different array elements, for untangling thedirectionality and elevation angle of the incoming waves. Forcharacterizing noise sources, beamforming is conventionally applied witha
