摘要
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。
Basing on the basic principle of Ground Penetrating Radar, the paper has discussed the influence of different datafilter parameter about Ground Penetrating Radar on image analysis result, and has got the result that Vertical bandpass filterplays a important role in settling the problem of Ground Penetrating Radar. Then according to pratical engineering exampleof ancient circumvallation of PingYao, concretely discussing the set up problem of Vertical bandpass filter, suggest thataccording to the true hydrology engineering and geology condition, select appropriate data filter parameter, in order to getclean and accurate image of Ground Penetrating Radar, supply basis and auspice to technical apply and exploration work infuture.
