| 摘 要： | 探地雷达是利用超高频脉冲电磁波探测地下介质分布的一种浅层地球物理勘探方法，探地雷达超高频、宽频带脉冲电磁波在地下有耗介质中的衰减特性是一个十分复杂的过程。本文从电磁波传播的麦克斯韦方程出发，较为系统地研究和分析了雷达脉冲电磁波在有耗介质中传播的衰减特性，对研究雷达脉冲电磁波在地下有耗介质中的传播机制有指导意义。

| Abstract: | Ground Penetrating Radar (GPR) is a new geophysical tool which generates super high frequency pulse electromagnetic wave used to detecting the distribution of underground media. The attenuation behaviors of GPR pulse wave with wide frequency band and high frequency in underground media are very complicated process courses. In this paper, from Maxwell's equations, the attenuation behaviors of GPR pulse electromagnetic wave propagation in heterogeneous medium are systematically studied and the obtained results are very useful for knowing the propagation mechanism of GPR pulse electromagnetic wave in underground hetorogeneous medium. |
