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 identification.
