SOURCE LOCALIZATION WITH A TWO-DIMENSIONAL FOCUSED ARRAY: OPTIMAL SIGNAL PROCESSING FOR A CROSS-SHAPED ARRAY

摘要

In order to overcome the poor performance of a focused cross-shaped array for 2-D localization, a new arrayprocessing method, based on discarding part of the array cross spectral density matrix, is presented. Numericalsimulations show that it leads to acoustic source images close to those obtained with a full square array. Thismethod will now be applied to experiments such as aerodynamic noise characterization in a wind tunnel.
