Dip-moveout (DMO) processing is usually based on the cosine-of-dip correction for movement velocity valid for homogeneous, isotropic media. Some recently developed DMO algorithms allow for a velocity gradient above the reflector, but still ignore anisotropy. Here, the author presents an analytic treatment of normal moveout velocities for dipping reflectors valid for a wide range of homogeneous anisotropic models including transverse isotropy with a tilted symmetry axis and symmetry plans in orthorhombic media.
