雷达遥感穿透次地表获取残存信息分析

ON RADAR WAVE’S PENETRATION AND ACQUIRING SUBSURFACE REMAINEDINFORMATION

分析了雷达波对干燥沙土的穿透深度δp 关系式并进行了理论计算 ,在阿拉善区可达 2 .82m以上的穿透深度 .利用美国航天飞机雷达遥感数据 ,进行穿透深度的实证分析 .该研究对于利用雷达遥感获取次地表残存信息进而进行古环境的分析具有重要意义 ,也充分表明雷达遥感在中国西北干旱区古环境研究中的巨大应用潜力 .

Based on Maxwell theory, the paper analysis radar wave's penetration depth((P) to arid sand and soil in Alaxa area, Inner Mongolia .Using shuttle radar remote sensing data, some examples ,such as old channels and old lake shore lines ,of penetration are shown. The study of penetration depth has an important meaning for acquired subsurface remained information and paleo environment reconstruction .Radar remote sensing will play an important role on paleo environment study in arid area of North west of China.
