摘要 本文根据简化的积分公式模型(IEM),分析了面散射过程中后向散射系数与地面参数之间的关系。利用航天飞机成像雷达(SIR-C)获取的极化雷达图像,提取新疆北部地区冲积扇的散射系数以及介电常数(湿度)与粗糙度。由图像获得的地面参数数据,可以用于分析冲积扇成因、时代以及期次的关系。 Surface parameters refer to the complex dielectric constants, moisture, surface rms height and coherent length, etc. This paper analysed the simplified one-step IEM Model, and estimated the backscattering coefficients, dielectric constants and surface roughness(rms height and coherent length) with the SIR-C L-band Polarimetric data for Xinjiang area. The surface parameters derived from polarimetric data can he used to analyse the forming courses, time and stages of alluvial fans.
