Abstract
Dipole array antennas with optical modulators are applied to directional borehole radar. Experimental results of 2-D source location are shown. In the experiments, two dipole antennas are set in a borehole as receivers, and a transmitter is located 0.9 m apart from the borehole. The 2-D MUSIC algorithm modified for array type radar in a borehole is applied to the measured data to estimate the location. Method of moment was used to model the antenna
