摘　　要： 研究了高炉密闭环境下,雷达测量料面和料层厚度的微波电磁特性.利用电磁计算学和CST仿真方法,研究了媒介层介电常数模型,高炉料面和料层模型的微波透射、反射和吸收特性,高炉布料层数、雷达波入射角度和雷达波频段与炉料媒介层介电常数重构关系模型.利用雷达波反射和透射电磁特性,结合高炉雷达的分布式雷达传感阵列,并利用焦矿媒介层存在介电常数差的特征,实现了高炉内料面形状和三层焦矿厚度在线3D重构. Microwave electromagnetic characteristics in radar measurements of burden surfaces and media thickness of an ore and coke （O/C） layer were researched in the closed environment of a blast furnace （BF）. With electromagnetic calculations and CST simulation software, a dielectric constant model of the media layer was developed to study the transmission, reflection and absorption characteristics of the burden surface and the O/C layer in BF. Also a reconstruction relational model of the number of distributing O/C layers in BF, microwave angle and frequency band concerned with the dielectric constant of the media layer was established. Using trans- mission and reflection electromagnetic characteristics of radar waves, combining with BF radar distributed radar sensor array installation and the different dielectric constants of the O/C layer in BF, the three-dimensional reconstruction imaging of burden surfaces and O/C layer thickness in BF was realized on-line.
