ANTENNA STRUCTURE OF GROUND PENETRATING RADAR FOR DETECTION SURVEY

摘要

The present invention comprises a waveguide for varying the impedance of the antenna between the main body of the transmitting antenna and the receiving antenna and the ground surface, and by moving the waveguide up and down, thereby adjusting the characteristic change of the transmitting and receiving antenna according to the state of the ground surface. It is characterized by providing the antenna structure of the underground burial detection radar in which the maximum efficiency for the transmit / receive antenna is shown and the transmit / receive antenna is minimized from the influence of the ground surface.;In addition, the present invention provides an antenna structure of the underground buried surveying radar for the transmission and reception antenna can be executed in an optimal operating state to facilitate the operation of the equipment even at the same time, even without skilled technicians to improve the operation efficiency of the equipment. It is.;In addition, the present invention can be installed and used to improve the overall efficiency to prevent the safety accidents that may occur in various underground constructions can be measured irrespective of the state of the earth surface so that the location of underground buried material can be easily confirmed To provide the antenna structure of the underground buried surveying radar for maximizing the satisfaction and reliability in use to the measuring instrument and the user.;Underground burial, ground surface, radar, GPR, transmit / receive antenna, waveguide, drive motor, impedance, feeder, limiter
