Enhanced-Semblance-Weighted High Resolution Radon Transform in T-X Domain

Radon transform has been applied to petroleum seismology and become a common technique in attenuation of multiples in seismic process for three decades. In this thesis, a high resolution Radon transform in t-x domain which is applied to common mid-point (CMP) gathers is introduced. This method uses time domain weighted semblance weights in the interest of time variation, is optimized by preferring energy to more significant p traces, and seems to yield higher resolution than other Radon transforms in frequency domain or of different algorithms. The proposed approach is tested on both synthetic and real NMO-corrected data.
