| 摘 要： | 钻孔雷达相比传统的地球物理方法具有更大的探测范围,可得到更多的地层信息。在地质雷达正演模拟的方法中,时域有限差分法能提高探测的效果和解释的准确性。将两者相结合,通过单孔反射测量对金属矿进行数值模拟及对结果进行分析,说明了单孔反射测量不仅可以确定矿体的位置,而且对矿体形态也具有很好的识别性。

| Abstract: | Compared with common geophysical method,the borehole radar can detect larger horizontal range,and it also can receive more strata information.During the GPR forward modeling methods,Finite Difference Time Domain Method(FDTD) can improve the effect of detection and the accuracy of interpretation.In this paper,we use FDTD to simulate the borehole radar detection by single-hole reflection survey method.By analysising result,single-hole reflection surveys on the ground floor has a very good target identificatio... |
