| 摘 要： | 宽带探地雷达系统以其高分辨率而受到重视。我们系统地分析、模拟和实验测试了宽带天线，在同络分析仪的基础上研究和开发了宽带的探地雷达系统。对不同模型进行探测，结果表明系统具有很高的分辨率。更重要的是该系统可以在与被探测介质不接触的情况下对介质内部进行探测，具有很高的工作效率。在工程质量检测中将具有巨大应用前景。

The broadband GPR system study and its application in engineer inspecting |
| |
| Abstract: | The broadband GPR system is regarded as a very important method in quality inspecting because of its high resolution. We analyzed and modeled the Vivaldi antenna and tested it by experiment, the results show that the antenna have very broadband frequency range and good directivity, then we develop the broadband GPR system based on Network analyzer. Three experiments are made to show that the system has very good detection results in resolution and accuracy. The research shows that the broadband GPR system will have wide application in engineering detection. |
