<p>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 (Ζ1) of said first frequency signal and a second absolute phase shift (Ζ2) of said second frequency signal, transforming Ζ1 to a first corrected absolute phase shift (Ζ1c) and Ζ2 to a second corrected absolute phase shift (Ζ2c) in accordance with an expected relationship between Ζ1 and Ζ2, and estimating moisture content from Ζ1c and Ζ2c.</p> |
