N2  - A new method of wave modelling and phase velocity filtering in the FX domain is presented. A shot record is considered to be consisting of two models ? one model is that of relatively slow velocity coherent noise whilst the other is of relatively fast velocity (reflected) waves. The process measures phase velocity as a function of frequency for each trace of a shot record. Then it produces the two separate models ? one with only coherent noise present, the other with only reflected waves present. This has a clear application to shot records on which coherent noise has the same frequency content as reflected signal, and the process requires less computation than the equivalent FK methods.
