RadExplorer
RadExplorer - is designed for interactive processing and interpretation of GPR data developed by DECO Geophysical.RadExplorer is a specially designed program for GPR (ground-penetrating radar) data processing and interpretation. The options set optimized for GPR data and friendly human-engineeredinterfaceallow quick and effective processing of GPR data.
Features:
•Automatic selection of optimum data processing parameters by default depending on the parameters of the data
•Interactive constructionof data processing flows with ability to save them on hard disk and re-use with other files
•Unlimited undo of the processing routines
•Interactive detemination of dielectric constant/velocity in the media and depth of target objects
•Reflection picking with saving the obtained picks into tabular text file
Flexible model editor and time-to-depth conversion
RadExProPlus
RadExProPlus is designed for comprehensive processing and interpretation of near-surface on-shore and off-shore seismic, VSP and GPR data under Windows 9x/Me/2000/XP/Vista.
Scope:
