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…

Uniqueness of an inverse source problem in experimental aeroacoustics
Thorsten Hohage, Hans-Georg Raumer, Carsten Spehr
This paper is concerned with the mathematical analysis of experimental methods for the estimation of the power of an uncorrelated, extended aeroacoustic source from measurements of…
