摘　　要：介绍了电磁波理论、粮仓体系正演模型的构建、模型参数迭代过程、粮食水分-介电模型.通过对连续剖面法的测量结果进行分析,得到电磁波的速度,结合介电-水分模型,反演出粮食含水量,进行实地试验,采集并分析了测试结果.实验表明了电磁波测量粮食水分是可行的.The amount of moisture in stored grain is an important factor which affects food safety. Therefore, a timely and accurate detection of the amount of moisture in stored grain is of great importance. Electromagnetic wave has a strong trait of penetrating, which is able to detect the amount of inside reactor moisture in the non- destructive case. The electromagnetic waves, construction of forward model in granary system, iterative process of model parameters, grain moisture-dielectric model were introduced. The speed of electromagnetic waves was obtained by analyzing the measurement of continuous section-scan method, and then the humidity of grain deducted by combining dielectric-moisture model. The results were collected and analyzed in the field test. It shows that the electromagnetic wave measurement of grain moisture is feasible.
