Laboratory Experimental Setup For Cross-Well Radar

Cross Well Radar is a technique that uses Ground Penetrating Radar, with antennas that are<br>lowered into sampling wells in-situ by cable. Radar waves are emitted from a transmitting antenna in<br>one well propagate through the ground to a receiving antenna in a second well to image the dielectric<br>properties of soils for detecting contaminants (such as DNAPLs). To better understand the physics of<br>CWR in soils, it is necessary to experimentally evaluate and validate the behavior of antennas in soil. A<br>proto-type model of infinite soil media is experimentally simulated by constructing a SoilBed facility.<br>The objective of this paper is to explain and evaluate different factors effecting experimental data<br>collection and calibrating the results. Depth, antenna installing problems, soil disturbance and boundary<br>conditions effects have been experimentally evaluated. Other (desired or undesired) transmission<br>coupling and paths were studied, and efforts were conducted to eliminate the undesired paths.
