Coaxial Impedance Dielectric Reflectometry
The Coaxial Impedance Dielectric Reflectometry (also referred to as “Ratiometric Coaxial Impedance Dielectric Reflectometry”) method of soil moisture measurement employs an oscillator to generate an electromagnetic signal that is propagated through the sensor by metal tines and into the soil. It characterizes the ratio of the amplitudes of reflected radio waves at 50 MHz with a …
