摘要
利用Radarsat-2雷达影像数据对裸露地表进行土壤水分的反演,通过数据模拟分析,建立经验后向散射模型,反演获得土壤含水量的模拟值与实测值进行相关性分析。结果表明,模拟值与实测值有着很好的相关性(R2=0.812 8),即可以利用Radarsat-2雷达数据进行大面积地表土壤含水的监测,并能取得较好的结果。
The inversion of soil moisture for bare surface was studied by using Radarsat-2 radar image data through analyzing the simulated data. The experience backscatter model was established. The simulated values of soil moisture content were in- versed. The results showed that there was a good correlation between simulated values and measured values （R^2=0.812 8）. It is indicated that the Radarsat-2 radar data could be used to monitor the surface soil water of the large area.
