Abstract

Aiming at the performance analysis of portable planar microphone arrays under different attitude angles in practical applications, azimuth estimation error of sound source associated with array attitude angle is derived. The influence from pitch angle and roll angle is formulated as an impact factor and the corresponding investigation is provided, leading to an explicit relationship between azimuth estimation error bound and tolerance range of array attitude angle. Comparison analysis and numerical results demonstrate that this study provides a quantitative approach to evaluate the azimuth estimation performance for portable planar microphone arrays when attitude angle is considered.
