Theoretical and measured DC pulse propagation of a borehole radar in a cross-hole mode is presented. Arrival times of measured signals are analyzed, and three modes of waves propagating among antennas and a suspending coaxial cable are determined. The first is a direct wave between antennas, the second is a guided wave on an outer surface of a logging cable, and the third is a directly coupled wave to the coaxial cable. Deformation of the radiation pattern due to the guided wave along a coaxial cable is shown. Loading ferrite cores on the cable reduces this guided wave.
