This paper describes the evolution of a promising new technique for subsurface remote sensing, geophysical diffraction tomography, from its theoretical formalism to its current state as a proven field technique capable of high resolution imaging of natural and buried subsurface features. The paper begins with a brief introduction of the concept of diffraction tomography and a review of the theoretical development of a scheme for implementing diffraction tomography in a geophysical imaging technique. Next, the field procedure is described. The final topic for this paper, and its primary objective, is to present results of three recent field tests of the system. 9 refs., 12 figs.
