What is RT?

RT stands for Radar Tomography shortened from CART. RT is a standard term for GPR surveys (or systems) that combine efficient radar surveying with precise positioning control and advanced signal processing that allows the creation of high-resolution radar images of the subsurface on a large scale. By "large-scale" and "high-resolution", we mean surveys covering thousands of square meters with a resolution of centimeters. Such images take on the quality of satellite radar images. In fact, in many ways, RT has more in common with (a scaled-down version of) satellite radar or 3D seismic imaging than with standard GPR profiling.

Another name used for RT that was used in the past is: GPiR, which stands for Ground-Penetrating imaging Radar.
