English abstract:
We investigate two different design methods for wideband beamformers with applications to microphone arrays. Our major design goal is to reduce the number of sensors while maintaining a good beamforming
performance. The different design methods considered are interpolated arrays with virtual sensors, and optimized sparse arrays. We present new optimization procedures for wideband beamforming with both types of arrays. Typical experimental results include array performance
in case of noisy sensors, and in the presence of simulated room reverberations.

German abstract:
Es werden veschiedene Methoden für das optimierte Wideband-Beamformer-Design mit Anwendungen bei Mikrofonarrays untersucht. Die vorgestellten neuen Methoden beruhen auf interpolierten Arrays mit virtuellen Sensoren und auf Sparse Arrays. Experimentelle Ergebnisse inkludieren Sensorrauschen und den Einsatz der Arrays in simulierten, akustischen Umgebungen.

Keywords:
