Abstract

The design is presented of an M:M multichannel seismic filter which passes and rejects information on the basis of the moveout of that information and which produces as many output traces as are input. The design is discussed in two stages, the first dealing with a filter which is able to handle specific moveouts only and the second pertaining to filters which work according to specified moveout ranges or windows. Two different window types are considered, viz. linearly bounded and hyperbolically bounded windows. Two examples of the filters are discussed and the results of their application to synthetic data are presented. Potential uses of the filter are: (1) prefiltering common depth point gathers prior to velocity analysis, and (2) filtering stacked or 100% coverage data, i.e. data for which there is no redundancy.
