On directivity factor of the first-order steerable differential microphone array
Abstract
Directivity factor (DF) is a fundamental performance measure of microphone arrays. This paper studies the DF of the first-order steerable differential array (FOSDA) whose response is constructed by a linear combination of monopole and two orthogonal dipoles using a four-element square array. The DF of the ideal FOSDA and the DFs of the FOSDA with microphone gain/phase errors are derived, all in closed forms. Based on the theoretical analysis, several findings regarding the properties of the DF of the FOSDA are obtained.
