Abstract
We present a high-frequency algorithm for the numerical solution of problems of wave scattering by bounded obstacles in three dimensions. The algorithm combines the use of an ansatz for the unknown density in a boundary integral formulation of the scattering problem with an extension of the ideas of the method of stationary phase. It relies on the fast Fourier transform for the high-order interpolation of the unknowns and is error controllable for moderate to very high frequencies with virtually fixed computational times
