Abstract	GPR is famous for its accuracy and portability in local subsurface investigation. Its capability is limited when considering large-scale or dangerous survey. Air-borne GPR characterized with speediness and remote sensing (contactless measurement), can overcome these shortages. Current airborne GPR can be classified into three types. The first suspend conventional commercial GPR antennas and control unit under a helicopter. The second type is fabricated for airborne survey, and has special hardware and system. The third type is synthetic aperture radar with penetrating capability. After summarizing the current airborne GPR, we simulated two models with flat or rough surface, respectively, for air-borne GPR measurement. Both the ground surface and the subsurface can be imaged clearly in two situations. It is concluded that air-borne GPR is a potential tool for subsurface measurement will receive more attention in the future.
