In the following link you will find the relation between moisture content, dielectric constant value, frequency and material type:

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19750018483.pdf

More detail about dielectric constant you may find in the link:

http://www.iai.ga.a.u-tokyo.ac.jp/mizo/seminar/colin.pdf

Taking into consideration that dielectric constant is directly related to the strength of the SAR back scatter signal, you will be able to do your job.
