Spatial dealiasing of 3-D DMO

The construction of a 3-D Kirchhoff dip moveout (DMO) operator for the constant-velocity case is remarkably simple in concept. First, generate the 2-D DMO operator between the source and receiver and then place it in the desired output 3-D volume along the trajectory between the source and receiver. Most of the literature concerning the design of such operators addresses the first step in the process, i.e., generation of the 2-D DMO operator. This paper treats the second part: sampling the 2-D DMO operator into the 3-D volume.
