In this work the algorithm for solving the direct diffraction problem by a numerical definition of the Kirchhoff integral on the basis of preliminary calculations rapidly oscillating kernel transformation considers. Estimated the gain in performance compared with the known algorithms, the possibility of calculating the characteristics of the field in a fixed plane analysis, in the space between the source of complex shape and the receiver, taking into account the influence of localized heterogeneities medium of propagation and shadowing effects of the radiator surface
