Surface-Related Multiples Elimination for Waterborne GPR Data

Ground-penetrating radar (GPR) is a well-respected, effective, and efficient geophysical technique. However, for underwater engineering detection archaeology, the measured B-scan profiles typically contain surface-related multiple waves, which can reduce signal to noise ratio interfere with interpretation of results. SRME feedback iteration method based on wave equation, frequently utilized in marine seismic explorations but very rarely GPR detection. To fill this gap, we applied suppress multiples that appear images. When compared effectiveness horizontal layered model undulating interface model, found high match rate between predicted real-world multiples. In addition, addition Gaussian random level 4% maximum amplitude profile stratified yielded satisfactory suppression Finally, section actual archaeological images achieve suppression, more effectively weaken inhibit Both numerical simulations field data show highly suitable interpreting waterborne data, accurate be obtained from after suppression.
