An embodiment of the present specification discloses a landmine detector. The landmine detector includes multiple electronic-controlled devices which change the resistance, inductive capacity and electrostatic capacity upon the applied signal, and may comprise a sensor unit detecting underground objects; and a circuit unit generating a first applied signal letting the sensor unit operate as a metal detector sensor, and a second applied signal letting the sensor unit operate as a ground-penetrating radar antenna sensor. [Reference numerals] (240) Input and output unit; (AA) Electronic-controlled circuit unit; (BB) Circuit unit of underground-penetrating rader; (CC) Circuit unit of metal detector |
