The amount of moisture in stored grain is an important factor which affects food safety. Therefore, a timely and accurate detection of the moisture content in stored grain is of great importance. Electromagnetic wave has a strong trait of penetrating, which is able to detect the moisture content of grain inside the heap in the case of non-destructive. This paper mainly takes the research of grain moisture permittivity and its mathematical model which is based on the ground penetrating radar electromagnetic wave technology. It introduces the radar electromagnetic wave theory, construction of granary system´s forward model, and the mathematical models of grain moisture permittivity. Through analyzing the results of the continuous section-scan measurement, we get the speed of electromagnetic waves. Then combining grain moisture-dielectric model, we calculate the dielectric constant of grain moisture. Further, we can get grain moisture content through the calculated dielectric constant. Under the guidance of the theory, we carry a field test, collect and analyze the results. It shows that the radar electromagnetic wave measurement of grain moisture is feasible and effective.
