| Abstract: | Abstract： In this paper, some major methods for measuring relative dielectric constants of media have been discussed in detail from theory to practice. These methods are applied to GPR (ground penetrating radar) exploration no matter whether its transmitting antenna and receiving antenna are separated or integrative. Tests show that these methods can meet the requirements in practical work. |
| Keywords: | ground penetrating radar relative dielectric constant determination method known objective depth method point source reflection body method common central point method layered reflection body method |
