摘要
The present invention provides a GPR (Ground Penetrating Radar) apparatus for a railway ballast track, comprising: a transmission antenna generating and outputting a GPR signal; a first receiving antenna positioned to be spaced at a predetermined distance from the transmission antenna in parallel with railway rails and receiving the GPR outputted by the transmission antenna; a second receiving antenna positioned to be spaced at a predetermined distance from the transmission antenna in a direction vertical to the railway rails and receiving the GPR signal outputted by the transmission antenna; and a third receiving antenna positioned to be spaced at a predetermined distance from the second receiving antenna in parallel with the railway rails and receiving the GPR signal outputted by the transmission antenna, wherein the railway rails are installed to be positioned between the transmission antenna and the second receiving antenna, and between the first receiving antenna and the third receiving antenna.
