Three-Dimensional Acoustic Source Mapping with Different Beamforming Steering Vector Formulations
Figure 5
Maps of relative sound pressure level contributions at the array centre (correct values are 0 dB, 1.7 dB, and −2.2 dB for source A, B, and C, resp.) using classic beamforming without deconvolution for steering vector formulations I–IV, Helmholtz numbers and , , crosses mark the projected position of the sources.
