Always on seismic data record, reflection event will be masked with Ground_roll and observation of this event is not usually easy. Radial trace transform is a simple transform for mapping x-t gathered data into apparent velocity and travel time domain. The apparent frequency of Ground_roll will be changed completely in RT domain. With knowledge of this changes and the application of frequency filters in RT domain, these events can be attenuated. In this paper the result obtained from F-K method and RT method on one common shot gather acquired from oil field has been compared. The results showed that the RT filters is much better attenuate those events with respect to F-K method without much reducing amplitude spectrum.
