Abstract
An angle-of-arrival estimator is derived for acoustic waves that propagate in atmospheric turbulence. The estimator directly accounts for the effects of random fluctuations in the propagation environment. The first and second moments of the sound field, as derived from the theory of wave propagation in a random medium, and realistic atmospheric turbulence models are utilized. Results using this estimator are compared to results using conventional beamformers that do not account for the effects of atmospheric turbulence.
