摘要：

Application of the Kirchhoff formula for subsonically moving surfaces to scattering of sound from a moving rigid body is described. The formulation leads to a singular integral equation that yields surface values of the field. The integral equation is solved using a boundary element technique in conjunction with the Galerkin method. Several checks on the accuracy and validity of the scheme are discussed. Numerical results are obtained for scattering of sound from a harmonic point source co-moving with a thin, winglike body.
