摘要 我们讨论了一种十米波长的机载雷达测深仪——暖冰探测探测器（WISE），它能在预计较高频率的雷达信号穿透受限的区域测量冰层厚度。在此我们报告了在格陵兰岛进行的三次（2008年、2009年、2010年）以及在南极洲进行的两次（2009年、2010年）科考活动的结果。与较高频率雷达数据的比较表明，在格陵兰岛冰层厚度测量的精度为±55米，在南极洲为±25米。我们还估算了格陵兰岛西南部卡西缪特叶瓣的冰层厚度，该区域此前很少有冰层厚度测量数据，这表明WISE能够穿透强散射环境。
Abstract We discuss a decameter-wavelength airborne radar sounder, the Warm Ice Sounding Explorer (WISE), that provides ice thickness in areas where radar signal penetration at higher frequencies is expected to be limited. Here we report results for three campaigns conducted in Greenland (2008, 2009, 2010) and two in Antarctica (2009, 2010). Comparisons with higher-frequency radar data indicate an accuracy of ±55 m for ice-thickness measurements in Greenland and ±25 m in Antarctica. We also estimate ice thickness of the Qassimiut lobe in southwest Greenland, where few ice-thickness measurements have been made, demonstrating that WISE penetrates in strongly scattering environments.
