A mine detector (1) serving for, by means of ultrasound, locating and identifying a mine (10) buried in the ground (9). The mine detector (1) comprises an ultrasonic transmitter (13) for transmitting ultrasonic signals (11) into the ground (9), at least three ultrasonic receivers (14; 15) for receiving reflected signals from the emitted ultrasonic signals (11), and at least one computer (19) connected to the at least one ultrasonic receiver (14; 15) for processing the signals. The three ultrasonic receivers (14) are placed at a distance both from the ultrasonic transmitter (13) and from each other. Between the computer (19) and the ultrasonic receivers (14; 15) is inserted a microprocessor (20, 21), and the computer (19) is programmed to, on the basis of the signals received from the microprocessor (20, 21), compute data representative of an image of the locality and configuration of the searched mine (10). The mine detector (1) is functioning with a high degree of security and can also be used for identifying mines (10) without metallic part, such as plastic and/or glass mines. |
