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。
In this paper, the satellite microwave SSM / Ⅰ remote sensing data of radiant temperature (TB) of 7 channels on farmland in North China Plain in northeast China in 1996 was proposed. The scattering index and polarization index of several channel TB combinations were proposed to analyze farmland in the plain of China Microwave radiation characteristics, and its seasonal changes with the growing season. On-board SSM / I data can monitor crop growth and changes in ground-level humidity in plain areas. The paper also gives the numerical simulation results of surface vector radiation transmission in the atmosphere and crop plants.
