ENVISAT ASAR数据用于水稻监测和参数反演

Rice Growth Monitoring Using ENVISAT ASAR Data

摘要: 用雷达后向散射模型模拟了水稻生长周期内入射角对雷达后向散射的影响关系。用模拟结果归一化雷达数据的后向散射系数,得到同一入射角下水稻周期内后向散射系数时间序列值。分析了归一化ASAR数据与水稻生物参数的关系,实验结果表明,ASAR数据可以用来估测水稻参数。

Abstract: The simulated results are used to correct(normalize) the radar backscattering from each data takes.The correlations between normalized radar backscattering and rice biophysical parameters are determined.The results show that ASAR data could be used to estimate rice parameters.
