The PC 20 has a communication unit inside and receives information transmitted from the landmine detection device 10.

  FIG. 2 is a schematic diagram illustrating a configuration example of a landmine detection device according to an embodiment of the present invention.

  The mine detection unit 100 detects a plastic mine by obtaining a dielectric constant from a coil-type metal detector 100A capable of detecting a metal object on the surface with respect to the mine detection area 30 and an electromagnetic wave radiated and reflected. It has a middle radar 100B, an odor sensor 100C that detects gas components such as hexogen and pen slits generated from gunpowder, and an infrared camera 100D that detects a temperature difference using infrared rays to detect objects having different specific heats. The mine detection unit 100 includes an antenna 130A connected to a built-in communication unit.

  FIG. 3 is a block diagram showing a configuration example of the landmine detection device according to the embodiment of the present invention.
