An Alias Protection Scheme for Radon Transform

C-11 AN ALIAS PROTECTION SCHEME FOR RADON TRANSFORM 1 Summary A variety of methods for seismic data processing based on the Radon decomposition are currently widely used in the industry. Due to finite spatial data sampling they usually suffer from aliasing that can substantially degrade their performance. The nature of aliasing is well understood (e.g. Turner 1990). Various methods for alias protection in Radon were suggested. Most popular among them imply dip-dependent low-pass filtering of the input data. A more recent approach (e.g. Herrmann et. al. 2000) applies scaling of the high-frequency components of the Radon transformed data. Here we
