Abstract
This work introduces new closed-form formulas to estimate an impinging emitter´s angle-of-arrival (AOA), based on data collected by different spatial configurations of a pair of acoustic particle-velocity and/or pressure sensors. This paper also identifies each such configuration´s corresponding validity-region for unambiguous estimation of the azimuth-elevation arrival angle.
