Side-scanning seismic: Analysis and a physical modeling study

Robert R. Stewart, Giovanni B. Marchisio

A processing procedure is presented here to use off-line energy (sideswipe), recorded on three-component (3-C) receivers, to create seismic sections. The processing procedure should include a polarization filter designed to enhance arrivals from particular off-line distances or angles. Filtered events from off-line distances can then be NMO-corrected, stacked, and migrated using full three-dimensional geometry. The procedure can be used to construct off-line sections. These methods are tested using ultrasonic, 3-C physical modeling data. The physical modeling data simulate lines offset from a buried reef. A migrated off-line section shows the reef.
