Interpretation of GPR data

This lecture i got it from dr Marta Kondracka Uniwersytet Śląski 

1. Create a file with Your Surname and Name as a Name of file, which will contain all the answers for next points.

2. Write a short essay about GPR methods (about 1 page - max. 2 pages) – description of the methods, applications, methods fixed offset profiling and CMP

3. Base on the catalog GPR_gr2 – list all files (file extension), which are created with the final GPR record – open them in the notepad and describe what GPR information they contain.

4. Open file “CMP example Hans” in RadExplorer – filter the data (DC removal, time-zero adjustment), using the “hyperbola” (toolbar) determine the dielectric constant/wave propagation velocity within the medium (3 hyperbola parameters) – save three images and copy it to Your project – describe them and compare obtained data with the data from table.

5. Open fixed offset profiling wrn.rad3 in RadExplorer filter the data using proper filters, using the model panel create one layer model for proper epsilon (using the information form the table and that the measurements were performed on the glacier) – copy it into Your file and describe it

6. Using the model panel create two-layer model for proper epsilon by creating new polygon (second layer) in model panel (using the information form the table and that the measurements were performed on the glacier) – copy it into Your file and compare it with the model from point 5.
