Radial Trace Transform

The radial trace transform is introduced by Jon Claerbout to produce significant separation of reflection signal and coherent noise

This technique allows effective attenuation of the noise using a variety of ordinary single trace operations in the radial trace domain.

Recent experience has shown that one of the more effective techniques for coherent noise attenuation is to model the noise by applying low-pass filter to the radial trace transform of an input gather, then to subtract the inverse transformed “modeled noise” from the original input gather.
