Modeling Dielectric-constant Values of Geologic Materials: An Aid to Ground-penetrating Radar Data Collection and Interpretation--Fig. 4

Fig. 4. Plot of dielectric constant versus maximum vertical imaging resolution for bistatic, dipole antennas with a bandwidth equal to 1 ± 0.5 of their center frequency. Typical dielectric-constant ranges for sedimentary rocks are shown as bars. The dielectric constant values are a summary of values given in Annan (1996), Daniels (1996), and Schon (1996).
