Abstract

See full text

The present invention relates to an air-coupled type bistatic ground penetrating radar (GPR) antenna and, more specifically, to an air-coupled type ground penetrating radar (GPR) antenna which reduces reception of a direct wave, which is a factor limiting imaging performance of a system when being received at a receiving side of the GPR antenna, by placing a loop antenna at a receiver point so as to be vertical to an antenna plane with respect to a polarization direction of a transmitting antenna and configuring a feeding direction to be orthogonal to a feeding direction of a transmitter and the ground surface. The air-coupled type GPR antenna, which is spaced apart from the ground, comprises: the transmitting antenna directed towards the ground and penetrating a radio wave into the ground; and a receiving antenna receiving a radio wave, which is radiated from the transmitting antenna and then reflected from the ground, and fed in a direction perpendicular to the ground surface and the feeding direction of the transmitting antenna. The transmitting antenna uses an antenna, such as a horn antenna, having directivity and the receiving antenna uses a loop antenna in which a physical plane of the antenna is positioned to be perpendicular to the ground surface with respect to the polarization direction, thereby resulting in the effect of improving radar detection performance of an air-coupled type GPR system.
