Three-Dimensional Acoustic Source Mapping with Different Beamforming Steering Vector Formulations

Figure 6

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 CLEAN-SC on a two-dimensional grid at , for steering vector formulations I-IV, Helmholtz numbers and , crosses mark the projected position of the sources.
