چکیده
In seismic reflection data analysis, noises are typically divided into coherent and incoherent. To increase data quality and recognize primary signals it is vital to attenuate these noises. Among which multiple reflections attenuation process is a serious challenge that a data analyst has to face.
Several Radon transform approaches have been widely thought and used by many researchers within the attenuating multiple reflections of seismic data. In this paper, parabolic radon remodels and their application in attenuating multiples reflections are performed. To validate the performance of the process, the method is applied to synthetic and experimental data consisting of two primaries and three multiples of first and second order. The results showed considerable attenuation of multiple reflection signals.

Abstract
In seismic reflection data analysis, noises are typically divided into coherent and incoherent. To increase data quality and recognize primary signals it is vital to attenuate these noises. Among which multiple reflections attenuation process is a serious challenge that a data analyst has to face.
Several Radon transform approaches have been widely thought and used by many researchers within the attenuating multiple reflections of seismic data. In this paper, parabolic radon remodels and their application in attenuating multiples reflections are performed. To validate the performance of the process, the method is applied to synthetic and experimental data consisting of two primaries and three multiples of first and second order. The results showed considerable attenuation of multiple reflection signals.
