Abstract
This poster session combines two related projects that ENSCO, Inc. has been involved in<br>during the past year. These projects are concerned with the ability to detect rather large<br>underground voids or targets at considerable depths in the complex geology.<br>The two related projects are:<br>1) The development of the Dahlonega Test Site (DTS) which is located in Northeast<br>Georgia, and<br>2) Our side-by-side comparison tests of the short pulse GSSI SIR-10 system with the<br>ENSCO developed synthetic pulse prototype system.<br>The synthetic pulse system is based on a stepped frequency concept as contrasted with the<br>impulse radar type. The rationale is that the synthetic pulse system allows the operator the ability<br>to “build” a time domain pulse with more effective energy than can be achieved by the conventional<br>short pulse (impulse) type system.<br>Other considerations include the increased emphasis on the higher frequencies (by the<br>potential of increasing the energy of these frequencies) thereby increasing the target resolution, and<br>avoiding those frequencies which may be detrimental to a nearby communication system, for<br>example.<br>As part of this poster session we will illustrate the DTS and its unique features, and then<br>follow this with our strategy in making our comprehensive comparison of the two ground<br>penetrating radar systems which we were evaluating.
