The Influence of the Geological Radar's Filter Parameters on the Results of the Graphical Analysis

基于探地雷达的基本原理,论述了不同地质雷达数字滤波参数对图像分析结果的影响,得出垂直带通滤波在雷达图像处理中起关键作用。并结合平遥古城墙的工程实例,具体探讨了垂直带通滤波的设置问题,建议根据实际的水文工程地质条件,选择合适的数字滤波参数,以便得到清晰精确的探地雷达图像,为今后的技术应用及探测工作提供了依据和支持。

Based on the fundamental principle of the ground penetrating radar, this paper discusses on the influence of different geological radar digital filter parameter on the results of the graphical analysis, and points out that the vertical band-pass filter plays an important role in the treatment of the radar image, and connecting with the practical engineering example of ancient circumvallation of Pingyao, probes into the problem of setting up the vertical band-pass filter, and puts forward some suggestions on selecting the suitable digital filter parameters based on the actual hydro-geologic engineering conditions for obtaining the clear and accurate image of the ground penetrating radar and supplying basis and auspice to technical application and exploration work in the future.
