The applications of airborne ground-penetrating radar (GPR) antennas or systems are not as widespread and well-developed as their counterparts, the conventional ground coupled antennas and While GPR airborne systems are not a novelty at systems. This has led to a situation in which airborne systems are normally used in a niche industry with very strict guidelines and expectations, such as the road surveying industry (Saarenketo and Scullion, 2000). Airborne antennas are, regrettably, often operated in very inefficient ways, sometimes disregarding basic physical laws or plain, fundamental principles of GPR technology. When the antenna is lifted from the ground a whole new set of problems and complexities arise and, if not taken into consideration, they can lead to very unreliable data and wrong interpretation of the obtained results.
