摘　　要：针对实际应用中对提高探地雷达分辨率的迫切需要 ,把fBm模型的分形技术引进探地雷达资料处理中 ,建立GPR的fBm模型。采用SRA算法进行GPR剖面分维计算。理论模型分析表明这是一种提取GPR高分辨率信息的有效方法 ,运用这一技术对工程实例进行了处理 。In order to meet the urgent demand of improving the resolution ratio of ground penetrating radar in practical application, this paper has introduced the fractal technology of the fBm model into the processing of the GPR data, and established the fBm model of the GPR. Adopting SRA method, we calculated the fractal section of GPR. The computational example shows that it is an extremely effective method for the extraction of high resolution information from GPR section, and its results are better than those from the routine processing method. In addition, we used this technology to tackle two engineering examples and attained fairly satisfactory result.
