WebProspecting [7], this is the duplex wave migration (DWM). This type of migration may be compared to the common migration the impulse response of which is turned through 90°. It enables to retrieve the duplex waves from the initial wave field. The waves are named duplex waves in case they have two reflections: the initial from the sub-horizontal WebApr 30, 2024 · Different from the previous approaches known as the prism-wave or the duplex wave method, our method uses random point scatterers instead of continuous reflecting boundaries (or mirror source) as new illumination sources and does not require the scatterer to be a true physical scatterer like a pinch out or a sharp edge point.

WebThe term duplex wave describes propagation paths with a double reflection involving a reflecting base boundary and a sub‐vertical feature. The purpose of this paper is to introduce the possibility of using duplex waves to directly … WebA: Duplex wave migration (DWM) operator differs from the PSDM one, as the Green's function in the Kirchhoff migration is formed in accordance with the law of propagation of the duplex wave. This leads to the fact that the impulse response of the DWM operator is rotated by 90 degrees with respect to the PSDM impulse response. flagship stores nyc
