Direction finding using a pair of orthogonally oriented velocity/pressure sensors
Yiu Lung Li, Yang Song, Kainam Thomas Wong · 2013
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.
