Kurzfassung
The delay-and-sum beamformer as a standard algorithm in microphone array analysis is described in this lecture. The algorithm is described for time-domain and for frequency-domain calculations. The dependency of the microphone array performance on the array design is discussed and a design strategy for arrays is proposed. In an extensive chapter the evaluation of closed and open test-section microphone-array measurements using the delay-and-sum beamformer is described. The introduction of advanced deconvolution algorithms to enhance microphone array results concludes the lecture.
