What is the GPR’s fuzzy zone? This is the shallow zone that is difficult to image with a GPR. This means that when the GPR puts out a signal, there is a portion of the immediate subsurface that is almost un-imagible (so I made up a word!). Many of...

Can you have an effect on the quality of your GPR (ground penetrating radar) data? ABSOLUTELY!!! In this video, I show how you can screw up your GPR data while on a survey. First you can create false positives with movements near your gpr antenna. For example, moving...

Filtering your GPR (Ground Penetrating Radar) data can help enhance your ability to identify and interpret targets of interest, or, it can destroy your ability to see targets of interest. Practitioners must be careful when applying filters so they do not remove...

How do you estimate depth of your GPR targets? How do you present depths to your customers? Do you present depths the same way in homogeneous soils as in heterogeneous soils? In this video I present the concept of Minimum Possible Depth (MPD) to help you cautiously...

What is the effect that 1 dielectric value has on your project? How off will your depth estimates be if you miscalculated by ONLY 1 dielectric value? Can the consequences be catastrophic? The effect of 1 dielectric value CAN have significant implications for your...
