| 摘 要： | 本文研究了星载微波ＳＳＭ／Ⅰ１９９６年在中国东北华北平原农田上７个通道辐射亮度温度（ＴＢ）的遥感数据，提出用几个通道ＴＢ组合的散射指数和极化指数来分析中国平原地区农田的微波辐射特征，及其随生长季节的时间性变化。星载ＳＳＭ／Ⅰ数据可以监视农作物的生长和平原地区地面湿度的变化。本文还给出了大气和农作物地表矢量辐射传输的数值模拟结果。

| Abstract: | Polarized brightness temperature(TB)data of the DMSP SSM/I over crop areas of the northern China in 1996 is studied. Some TB indexes, such as scattering, polarization and crop monitoring indexes, are defined and applied to the analysis of temporal variation of thermal emission from crop areas. This paper provides a novel approach to analyze the functional dependence of polarized microwave TB data on atmospheric and surface conditions during crop growth. It also presents a numerical simulation of vector radiative transfer equations with multiple scattering for a vegetation/snow model at SSM/I channels. |
