有许多技术可以聚焦原始的B扫描探地雷达（GPR）图像，这些图像主要是由于众所周知的双曲色散而失真的。在这项研究中，我们应用双曲线求和（HS）型聚焦技术在C波段频率的模拟和测量的GPR数据。建议HS方法的制定。利用物理光学模拟程序生成了不同金属目标的数值探地雷达图像。借助频率步进雷达系统构建了一个实验装置，并生成了相应的B扫描图像。将建议的HS方法应用于实测的B扫描GPR数据。对模拟数据和实验数据进行了聚焦成像。© 2007 Wiley Periodicals，Inc.

There are many techniques to focus raw B‐scan ground penetrating radar (GPR) images mainly distorted from well‐known hyperbolic dispersion. In this study, we apply a hyperbolic summation (HS)‐type focusing technique to the simulated and measured GPR data at C‐band frequencies. The formulation of the proposed HS method is presented. Numerical GPR images for different metal targets are generated by the help of a physical optics simulation code. An experimental set‐up is constructed with the help of a stepped frequency radar system and corresponding B‐scan images are generated. Proposed HS method is applied to the measured B‐scan GPR data. Focused GPR images of different objects were obtained for both the simulated and the experimental data. © 2007 Wiley Periodicals, Inc.
