Overview of foliage/ground penetration and interferometric SAR experiments

摘要

Abstract: This paper describes foliage/ground-penetration radar experiments and interferometric synthetic aperture radar experiments sponsored by the Advanced Research Projects Agency in 1992-3. In the foliage/ground penetration experiments, airborne synthetic aperture radar data have been collected at a variety of sites in three bands, 20-90 MHz, 100-500 MHz, and 1200-1300 MHz. Foliage penetration data were collected on Panamanian rain forest and on Northern Maine woods, and ground penetration data were collected on buried objects in a desert site in Arizona. Interferometric SAR data have been collected on various terrain to extract terrain height, and on military vehicles such as tanks and trucks to assess the utility of height information for target detection and recognition. !2
