Soil moisture retrieval from SAR

Image processing steps

• slant range correction

• speckle reduction (multi-looking)

• inversion modeling (physical model) to obtain soil dielectric constant ?

• conversion of ? into %Vol with 3rd order polynomial (e.g. Topp et al. 1991)

• grouping into 5% classes

• raster-to-vector conversion or raster use in GIS
