Radial trace computational algorithms at CREWES
David C. Henley
In another chapter in this report we introduced the use of the radial trace domain for coherent noise attenuation and demonstrated it on both real and synthetic data (Henley, 1999, 1, 2). This chapter describes the ProMAX modules we have written to perform the radial trace transform and its inverse, and to perform other useful radial trace operations. We consider some of the underlying issues involved in implementing the radial trace transform as a discrete mapping algorithm and give heuristic arguments for our programming choices. For each module, key parameters are discussed and criteria given for their selection. Some future research opportunities are outlined as well, based on these modules and their capabilities, which extend somewhat beyond the standard radial trace regime.
