| 摘 要： | 本文从理论推导电磁波在三层导电介质分界面的反射系数，说明电磁波的阻抗变换作用对地质雷达的探测效果有影响，并且详细分析了电磁波的阻抗变换对地质雷达的影响因素，最后得出结论：在使用地质雷达时，应根据实际情况选取工作中心频率来避开电磁波的带阻影响.

| Abstract: | From the Electromagnetic wave theories,we get the reflective coefficients of the electromagnetic wave on the interface of the three layers conductive media.And though the results,we know that there is no reflection on some interface of the conductive media.It is called impedance transform of electromagnetic wave.We can not get or can not get correct result in ground-probing-radar in some conditions.We must get some correct choice to avoid the belt resistance affection of the electromagnetic wave in ground probing radar working. |

| Keywords: | ground probing radar impedance transform belt resistance |
