Webcan be described by the Kirchhoff integral in the so-called single-scattering, high-frequency approximation (see, e.g., Bleistein, 1984; Frazer and Sen, 1985). The re … WebTwo classical flaw scattering models have been previously evaluated and implemented in the CIVA platform developed by CEA/LIST to deal with planar defects: the geometrical theory of diffraction (GTD) and the Kirchhoff approximation (KA). These two approaches appear to be complementary.

Web11 jul. 1999 · No.99CH37010) In this paper a Kirchhoff-based model is employed to determine the scattering from natural surfaces. Natural (rough) surfaces are described … Weblation of Born and Kirchhoff scattering allows us to take into account general scatterers as well as the nonlinear dependence of reflection coefficients on the medium parameters. The latter allows the treatment of scattering up to grazing angles. The outcome of the analysis is a characterization of the singular part of seis-mic data. twenty five ingredient meatloaf
