Estimation of surface soil moisture and roughness from multi-angular ASAR imagery in the Watershed Allied Telemetry Experimental Research (WATER)
Estimation surface soil moisture roughness multi-angular ASAR imagery Watershed Allied Telemetry Experimental Research

Radar remote sensing has demonstrated its applicability to the retrieval of basin-scale soil moisture. The mechanism of radar backscattering from soils is complicated and strongly influenced by surfac...
水稻多生长在温暖潮湿的多云多雨地区, 使雷达遥感成为水稻遥感监测的重要手段之一. 因此, 提出应用多时相、多极化ENVISAT ASAR数据进行区域水稻估产的方案. 首先利用ASAR数据进行水稻制图, 提取水稻种植分布图和多时相水稻后向散射系数. 随后, 基于像元尺度, 采用同化估产方法, 以LAI为结合点, 将水稻作物模型ORYZA2000与半经验水稻后向散射模型结合, 建立嵌套模型模拟多时相水...
