Abstract

The invention belongs to the related technical field of ground penetrating radars, and discloses a hybrid-loaded dual-polarized ground penetrating radar array antenna, which comprises a vertical polarized antenna group, a horizontal polarized antenna group and a radio frequency switch, the vertical polarization antenna group comprises a vertical polarization transmitting antenna and a vertical polarization receiving antenna of which the backs are provided with shielding cavities; the horizontally polarized antenna group comprises a horizontally polarized transmitting antenna and a horizontallypolarized receiving antenna of which the backs are provided with shielding cavities; and the vertical polarization transmitting antenna and the horizontal polarization transmitting antenna are connected through the radio frequency switch. And the vertical polarization receiving antenna is connected with the horizontal polarization receiving antenna through a radio frequency switch. The the detection capability of a conventional single-polarization ground penetrating radar can be effectively improved, more underground heteroplasmon information can be obtained, two radar images can be obtainedthrough one-time detection, and the detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the related technical field of ground penetrating radar, and more specifically relates to a dual-polarization ground penetrating radar array antenna with mixed loading. Background technique [0002] As an advanced non-destructive detection technology, ground penetrating radar has the advantages of high detection accuracy, wide application range, convenient portability and high efficiency. It is widely used in bridge detection, road surface quality detection, concrete reinforcement diameter prediction, underground pipeline detection, Trunk cavity detection, glacier thickness detection, underground metal and non-metal unexploded detection, geological crack detection and underground pollutant monitoring, etc. [0003] Ground penetrating radar technology originated in the early twentieth century and developed rapidly in the middle and late twentieth century. However, my country's GPR research started relatively late, focusing on t...
