| 摘 要： | 针对GPR剖面中存在的绕射波影响资料处理和解释问题,根据雷达波波动方程和声波波动方程在形式上的一致性,合理地将地震勘探中成熟的相位移波动方程偏移法、克希霍夫积分偏移法和有限差分波动方程偏移法引入到GPR资料处理中。理论模型的试验和实测资料的处理分析表明,该方法有较好的效果。

| Abstract: | Due to the interference of diffraction wave in GPR profiles, especially in the detection of underground pipes, caves or similar anomalies, the processing and interpretation of GPR data have become very difficult. In order to deal with this problem, the authors, according to the unified wave equation form of electromagnetic wave equation and sound wave equation, used three migration methods to process GPR data. They are phase displacement, Kirchhoff integral and finite difference, which had been employed extensively in data processing of seismic prospecting. On the basis of testing and analyzing the model, the processing and analyzing of the filed GPR data yielded good results. |
