The far-field acoustic radiation due to the interaction of upstream, unsteady vortical disturbances with an airfoil in subsonic, compressible flow is calculated using potential theory. A Kirchhoff surface is placed in the near field surrounding the airfoil and the pressure on this surface is calcula
## Abstract The problem of rapid farβfield computation from nearβfield samples acquired on a planeβpolar geometry is addressed in this paper. A fast processing algorithm is developed which uses the fast Fourier transform and the related shift theorem, by exploiting the convolution property of the r
