The Army Research Laboratory has been investigating the potential of low-frequency, ultra-wideband radar to provide part of the solution to the very difficult mine detection problem One of the issues associated with using this type of radar is that it spans a very wide frequency range and angular space, making it difficult to use `normal' calibration techniques. Thus, ARL has been investigating techniques to calibrate the ARL ultra-wideband BoomSAR data to gain a better understanding of the signal response from clutter, mines, and other targets of interest. In this paper, we present results from data collected in Yuma Proving Ground on various types of mines. In particular, we compare the radar cross-section of the mines, predicted using method of moments models versus the measured response from the mines, as indicated by the calibrated ultra- wideband radar imagery.
