摘要
采用麦克斯韦方程的解析解对位于地表上方一定高度处的电偶极源响应进行研究。设计了五种不同参数的地球模型,分别模拟均匀的湿混凝土、干混凝土、湿泥土、干泥土和水媒质,用于分析不同媒质条件下天线与地面间电磁场的响应特征。通过对不同介质模型条件下天线不同离地高度时的电磁响应的计算和分析,得到了一些重要的认识,对探地雷达天线系统的设计具有指导意义。
Electromagnetic responses of an electric dipole over the earth surface are studied. Five different earth models, which simulating the wet concret, dry concret, wet clay, dry clay and water respectively, are set to analyse the behaviors of the electromagnetic fields between the antenna and ground. Calculations are made for various heights of antenna offseft from ground and some important knowledge is obtained through this study for guiding design of ground penetrating radar system.
