Subband prescreening of foliage-penetrating SAR imagery

摘要

Abstract: In this paper we present the results of an empirical study investigating subband prescreener detection. The prescreener is used with ultra-wideband foliage penetrating synthetic aperture radar imagery. Our results demonstrate that, for the selected set of computationally simple features, lower resolution imagery can be used at the early detection stages. We also present initial multiband detection results. These results indicate that a combination of lower resolution subbands can be used in a fast prescreening algorithm without appreciable performance loss when compared to the fullband detector.!12
