UAV-BASED TWO-POSITION GROUND PENETRATING RADAR FOR OPERATIONAL MONITORING OF SUBSURFACE WATER RESOURCES

This paper considers the implementation of a two-position ground penetrating radar (GPR) located on board unmanned aerial vehicles (UAVs) and designed for operational search groundwater in arid desert regions Mongolia, which is an extremely urgent task. With help synthesizing GPR antenna aperture UAV, significant increase information content achieved compared to existing GPRs, since it becomes possible obtain panoramic image subsurface layers probed medium with required resolution sufficiently wide swath. On other hand, necessary efficiency (required, example, when monitoring vast areas) can only be field view created basis sounding principle, where emitting receiving signals are formed processed UAVs different or equal heights flying same speed spaced orthogonally direction their movement, makes use quasi-mirror reflection. In this case, swath will noticeably larger than case nadir sounding. condensed form, article following issues: model aquifer, geometry mode, up features (Doppler narrowing radiation pattern) antenna, resolution, potential reliable detection aquifer horizon, accuracy measurements its depth, as well need experimental work test theoretical provisions.
