摘　　要：对探地雷达数据进行合成孔径处理可提高探地雷达图像的分辨力 ,有利于对地下目标的探测及精确定位。文中提出了一种新的stolt偏移插值实现方法 ,用于探地雷达合成孔径成像 ,它能克服传统方法中偏移能量不集中的缺点并保持处理速度快的优点 ,通过对实测数据进行处理 。Synthetic aperture processing for ground penetrating radar data can improve resolution of radar image, and increase locating accuracy of buried objects. This paper presented a new stolt migration interpolation method for ground penetrating radar synthetic aperture imaging. This method can overcome shortcoming of migration energy out of focus by using conventional methods, and preserve merit of fast processing speed. The processing results of measurement data show that the proposed method is very effective.
