Abstract

A series of forward-looking ground penetrating radar measurements were taken that bracketed the emplacement of mines at a controlled test site. Fully polarimetric data were collected over a broad rang of frequencies at several times that spanned placement of the mines. These data have been used as input to chagne-detection processing both to examine the overall improvement in signal-to-clutter ratio provided by change detection and to begin assessment of the effects of weather and other relatively long-term variables on its effectiveness. Measurements have been performed initially with the system in a fixed position in order to determine base signal-to-clutter levels given ideal image registration. Under these controlled conditions, change detection is shown to be very effective over the short term in an application such as this. Changes in surface texture are also evident following the emplacement of mines. Morphological closing is shown to be a useful technique for delimiting such regions.
