Gaussian beams are often used to represent Green’s functions in threedimensional Kirchhoff-type true-amplitude migrations because such migrations made using Gaussian beams yield superior images to similar migrations using classical ray-theoretic Green’s functions. Typically, the integrand of a migration formula consists of two Green’s functions, each describing propagation to the image point —one from the source and the other from the receiver position. The use of Gaussian beams to represent… CONTINUE READING
