2025年2月9日 · Extending least-squares reverse time migration (LSRTM) to tilted transverse isotropic (TTI) media (TTI-LSRTM) improves imaging accuracy. However, TTI-LSRTM …

Abstract: Least-squares reverse-time migration (LSRTM) is linearized inversion based on the Born approximation, which commonly seeks to high-quality migration result by the least-squares …

Least-squares reverse time migration (LSRTM) is a powerful tool in seeking broadband-wavenumber reflectivity images. It produces better images over reverse-time migration (RTM) …

Abstract: This study develops prestack least-squares reverse time migration (LSRTM) for high-resolution ground-penetrating radar (GPR) imaging and compares its performance to standard …

2023年5月25日 · Least-Squares Reverse-Time Migration (LSRTM) is a common tool used to compute such images. Still, its high computational costs have led seismologists to use target …

Least-squares reverse time migration (LSRTM) is currently one of the most advanced migration imaging techniques in the field of geophysics.
