Further results on mainlobe orientation reversal of the first-order steerable differential array due to microphone phase errors

Abstract

In our previous work, we have revealed the phenomenon of mainlobe orientation reversal (MOR) suffered by the first-order steerable differential array (FOSDA) due to microphone phase errors. However, only a deterministic analysis is conducted in that work. To provide useful guidance for practical FOSDA design, this paper further studies the problem of MOR in the presence of uncertain microphone phase errors from two perspectives, i.e., interval analysis and statistical analysis. In particular, two criteria are derived to facilitate the FOSDA design in order to avoid undesirable MOR.
