| Abstract: | The measuring principle and characteristic of microwave moisture content determination techniques are analyzed, and a method is addressed as well.According to the relationship among the power attenuation, signal parameter variation and moisture content of grain when the microwave penetrates the grain, a model of microwave moisture content measuring system is built,Experiments are made to compare the algorithm with traditional method on solving this problem.The results show that this method can measure the grain moisture content quickly and efficiently, and satisfy the requirement of grain moisture content determination in grain depot. |

| Keywords: | microwave grain moisture content measurement dielectric constant non-destructive detection |
