摘　　要：基于脉冲体制探地雷达天线原理,针对混凝土结构探测的需求,以变形领结天线为基础,设计了一种双极化、多天线的探地雷达天线阵列,该天线阵列具有0.75~2.25 GHz的频带宽度,且方向性良好。该天线阵列不仅可以提高雷达系统的探测深度,也提高了雷达的探测效率。设计的天线阵列已成功应用于成像探地雷达项目中,对工程质量检测具有重要意义,为探地雷达三维成像设备的进一步开发提供了强有力的技术支撑。Based on Impulse Ground Penetrating Radar(GPR) antenna theory, and according to the requirement of concrete structure detection, This thesis designs a kind of dual?polarized multi?antennas array. The designed antenna array possesses 0.75~2.25 GHz fre?quency bandwidth and good direction. The double polarization enables deeper surveying, and enhances the efficiency of detection. The designed antenna array is successfully applied to three imaging GPR project. The design method is significant for project quality inspec?tion and provides effective support for the design of 3D GPR systems.
