Abstract
Among all possible algorithms of spatial filtering Radon transform is mostly used to separate signal from interfering noise that has big amplitude and minor T-X curve difference. The quality of the filtration can be significantly improved by using the algorithms that calculate the contribution of the different components of the direct Radon transform spectrum in the general wave field. This paper proposes the use of seismic signal model with variable amplitude when performing filtering with the use of Radon transform. This model has some advantages for different components of the wave field separation in comparison to the regular wave field local summation and enables a more detailed estimation of the seismic wave model.
