Geophysical diffraction tomography: A complementary remote sensing technique for hazardous waste site characterization.

摘要

Use of surface geophysical methods for characterization of hazardous waste sites has well documented technical, health, and cost benefits when compared to intrusive data gathering methods. This statement is obviously predicated on the assumption that the geophysical methods being employed are applicable to the waste and shallow geologic features in the area of interest. This paper places a new surface geophysical technique, geophysical diffraction tomography, into a context of its utility within the existing remote sensing technology. A procedure based on analyses of the propagating wave which accounts for the naturally occurring diffractions has more information available than simple time of travel, and therefore can provide information concerning subsurface features not recoverable from many existing surface sensing methods. The paper presents field results showing the application of the geophysical diffraction tomography method within the existing suite of remote sensing methods to maximize the site characterization information obtained. 18 refs., 4 figs., 1 tabs.
