Evaluation and interpretation of DARPA backgrounds ground-penetrating radar (GPR) data collected at Ft. A. P. Hill Virginia and Ft. Carson Colorado

摘要

DARPA sponsored a program during the fall of 1996 to collect backgrounds data (clutter and simulated targets) using several sensor systems. This paper focuses on the processing and interpretation of ground-penetrating (GPR) data collected using the Coleman ToMAS GPR system. High-resolution images generated using a backpropagation imaging (BPI) algorithm are presented for calibration lanes at two sites: one at Ft. A. P. Hill, VA, and the other at Ft. Carson, CO. Separate co- polarized and cross-polarized images are generated and compared. High-resolution cross-polarized images are also generated for an entire 100 meter $MUL 100 meter 'center square' area at one site in 0.1 meter depth intervals. Comparison with Geonics EM-61 magnetometer as well as dig results are also presented.
