Description

Migrate the GPR data (time-to-depth conversion accounting for the topography).

Usage

## S4 method for signature 'GPR'
migration(x, type = c("static", "kirchhoff"), ...)

## S4 method for signature 'GPR'
migrate(x, type = c("static", "kirchhoff"), ...)

Arguments

type	Either static or kirchhoff. See Details.
max_depth	maximum depth to appply the migration
dz	vertical resolution of the migrated data
fdo	dominant frequency of the GPR signal

Details

• static a trace-by-trace time-to-depth conversion that shifts the traces vertically according to their elevation.

• kirchhoff Topographic Kirchhoff migration (a Krichhoff migration that accounts for the topography). See Dujardin and Bano (2013) Topographic migration of GPR data: Examples from Chad and Mongolia, Comptes Rendus Géoscience, 345(2):73-80. Doi: 10.1016/j.crte.2013.01.003

Fresnel zone (used in the Kirchhoff migration) is defined according to Perez-Gracia et al. (2008) Horizontal resolution in a non-destructive shallow GPR survey: An experimental evaluation. NDT & E International, 41(8): 611-620. doi:10.1016/j.ndteint.2008.06.002
