Applied Physics and Mathematics Annotation << Back Compact GPR-SAR A.I. Kanaschenkov S.A. Zaikin V.G. Reutov The problems of development and technical configuration of the helicopter compact GPR with synthetic aperture (GPR-SAR), which is an effective tool for monitoring natural and man-made objects in problem solving nature, economics and management, and the prevention and elimination of consequences of natural and man-made disasters. Domestic and international experience shows that aviation GPR, including GPR-SAR, can perform tasks such as searching aquifer soil, ice monitoring, detection of subsurface radio-objects (such as pipelines), the detection of objects hidden by vegetation, biomass estimate and a number of others. The results of field experiments and mathematical modeling, obtained during the development of the layout compact GPR-SAR, which showed the ability to create a mock radiocontrast detect subsurface objects and objects hidden terrain. The proposed small-size helicopter GPR-SAR can also be placed on the car and provide study subsurface facilities located near roads on steep terrain.
