Radon transformations for removal of noise from seismic data

Abstract From the Canadian patent

Methods of processing seismic data to remove unwanted noise from meaningful reflection signals are provided for. Assembled seismic data are transformed from the offset-time domain to the time-slowness domain using a Radon , transformation. An offset weighting factor x n is applied to the amplitude data, wherein , 0 < n < 1. The coherent noise content of the transformed data is enhanced and , the , primary reflection signal content diminished by filtering at least a subset of the , transformed data. The filtered data are inverse transformed from the timeslowness , domain back to the offset-time domain using an inverse Radon transformation and , an inverse of the offset weighting factor …
