VMMD_MS Vehicle Mounted Multiple Sensor Mine Detector

General Information

The Multisensor Detector VMRV40 is a customized system for the detection of metal objects (by EMI*) and non-metallic objects (via GPR*) having a minimum size of approx. 10 cm diameter in the ground. The sensors are mounted on a flexible mat. This mat is fixed to a vehicle by means of a non- metallic construction in such a way that the sensors are moved close to the surface to detect objects in the ground. Maximum driving speed of the vehicle: 10 km/h.

The flexible mat ensures also on uneven surface a good ground contact without too much pressure to activate AP mines with pressure sensors.

In order to have a search width of 2.5 meters for the detection of objects having a minimum size of approx. 100 mm, the GPR-Detector must be equipped with 40 antennas. The antennas are arranged with a certain offset sidewise and lengthwise in such a way that there is no detection gap in driving direction.

For the same search width the Metal Detector has 20 search heads which are also arranged with a certain offset sidewise and lengthwise.
