ABSTRACT:
There is disclosed a method of estimating moisture content in a material involving directing a first frequency (f1) signal and a second frequency (f2) signal through a material, determining a first absolute phase shift (φ1) of the frequency signal and a second absolute phase shift (φ2) of the second frequency signal, transforming φ1to a first corrected absolute phase shift (φ1c) and φ2to a second corrected absolute phase shift (φ2c) in accordance with an expected relationship between φ1and φ2, and estimating moisture content from φ1cand φ2c.
