Advanced Techniques for Landmine Detection using UAV

This paper presents a bistatic ground penetration radar study with different transceiver and receiver antennas configurations. It is based on a design of air-coupled, miniature, low-power pulsed time-of-flight radar with TEM antennas. The goal was to develop a fully polarimetric bistatic radar attached to 2 separated drones flying in an optimal formation for target detection. The work introduces several experiments in the laboratory environment, where the flight formation with spatial positions of a transmitter and receiver antenna was observed. Achieved results show the optimal position of transmitting and receiving bistatic radars antennas. The goal is to detect small targets with an approximate surface of 0.01cm2, like anti-personal land mines. The bandwidth of the radar was 2 GHz. The goal is to enable tomography using drone-based GPR.
