STUDY OF INTERACTION OF SUPER HIGH FREQUENCY WAVES WITH GRAIN
Keyword(s):
The paper considers the interaction of ultrahigh-frequency waves with moist grains, in which the moisture information is represented as a function of two variables: the attenuation and phase shift of the electromagnetic wave. Wet material is represented as consisting of three flat layers: water, dry matter and air. Based on uncomplicated calculations, the conversion functions are derived and the influence of moisture, temperature and density coupling forms on the error of moisture conversion is studied.
