Yes ! It is possible to process GPR data wit SU to apply all the power of seismic processing tools to GPR data.

The basic trick is to fool SU by using micro second as the time unit and centimeters instead of meters. This way :

• frequencies are in MHz
• velocities range from 3330 cm/micro sec (water) to 30000 cm/microsec (air)
• offset are not badly truncated

There is no unified GPR data format and each manufacturer produces its own files. GPR data need to be imported from the manufacturer's format to SU format using the right tool.

• For Sensor&Software devices you can use the dt1tosu tool included in SU
• For Malå devices you can download a shell script here
• For other manufacturers, ask for the detailed format information and share the tool !

Once the data are converted to SU format, you will probably need to adjust the geometry using tools like sushw and/or suchw
