Ground Penetrating Radar Antenna Alignment for Potato Detection

Ground penetrating radar (GPR) is an emerging technology for crop monitoring and assessment in agriculture. The performance of GPR is directly related to its antenna radiation patterns. In this paper, the effects of bowtie antenna alignment is investigated for potato detection from the side of the ridge. Bowtie antenna shows different patterns in its E-plane and H-plane. This difference result in distinct performance with different antenna alignments. Simulation results suggest that the best detection sensitivity can be achieved by aligning the bowtie antenna’s long axis with the scanning direction and stacking the antennas in the short axis direction.
