Beamforming for measurements under disturbed propagation conditions using numerically calculated Green's functions
Marius Lehmann, Daniel Ernst, Marc Schneider +2
Beamforming methods for sound source localization are usually based on free-field Green's functions to model the sound propagation between source and microphone. This assumption is…

Weighted Data Spaces for Correlation-Based Array Imaging in Experimental Aeroacoustics
Hans-Georg Raumer, Carsten Spehr, Thorsten Hohage +1
This article discusses aeroacoustic imaging methods based on correlation measurements in the frequency domain. Standard methods in this field assume that the estimated correlation…
