Antenna is one of the core components of ground penetrating radar, which has a decisive impact on its selection and imaging accuracy. This paper comprehensively analyzes and compares the working principle, parameters, advantages and disadvantages of existing antennas, proposes a fast antenna selection method suitable for tunnel detection, and carries out numerical simulation and experimental research. Finally, a set of antenna parameters suitable for ground penetrating radar in tunnels is obtained, and ideas and methods for optimizing antenna design under different circumstances are proposed.Keywords: ground penetrating radar; antenna selection; imaging research; non-destructive testing一、讨论背景和意义随着城市地下空间的建设不断推动，隧道在城市交通、水利、矿业等方面扮演着越来越重要的角色。然而，隧道在建造和使用过程中，可能会受到地质灾害的威胁和破坏，如地面塌陷、滑坡、岩爆、水灾等。因此，隧道探测技术的进展和应用越来越受到重视。精品文档---下载后可任意编辑隧道探地雷达是一种通过电磁波辐射和反射与物质相互作用，探测并识别地下构造信息的非破坏性检测技术。其优点是能够快速、准确地猎取地质信息，不会对环境和人员造成危害。天线是隧道探地...
