MECHEM Detection System – MVMMDS
The MECHEM Vehicle Mounted Metal Detection System (MVMMDS) incorporates a CASSPIR Mine protected Vehicle (MPV) as the system carrier and utilizes a magnetic pulse induction metal detection system for the detection of metal objects under the ground surface.
The CASSPIR (MPV) is one of the first commercially built Mine Protected Vehicles (MPVs) in the world – and still is a world leader in its class.
The MVMMDS uses an electronic pulse induction metal detection system with sensors mounted on a durable non-metallic (rubber) draw-mat that is drawn behind a suitable Mine Protected Vehicle (MPV).
The draw-mat is towed behind the vehicle and can be configured to be drawn in the center or to the left- or right side of the vehicle. This versatile repositioning option makes the detection system ideal for roadside sweeping operations.
The rear-mounted detection suite is motivated by operational experience proving the inefficiency of any forward mounting of the sensors. The MPV protects the crew against any injury/death in the event of a mine blast – and any damage to the vehicle can be quickly/economically repaired.
The system comprises three basic elements. The first is the actual electronic detection, the second the signaling and record capacity and lastly the physical marking of the position of the detected item with white marking fluid on the ground.
The detection coils are mounted on foam rubber mats that are positioned on to the rear end of the draw-mat. Upon detection of a metal object, an electronic signal is sent to the control console inside the vehicle. At the same time a signal is passed onto the marking system and the ground is marked in real time with white bio-degradable marking fluid over the exact position of the detected metal object.
The system has been operationally proven on MECHEM contracts over the world. It has a proven ability to detect anti-tank landmines such as the TM 46 and TM57 at a depth of 1,200-mm in rocky shale soil and at speeds of up to 20 km/h (although it is never used at this speed). The standard search path is 2,200-mm wide. This width can be increased to 3,000-mm if the terrain/road allow this.
The preferred speed for the system is 5 km/h. At this speed the MVMMDS has no difficulty to accurately detect and mark TM46 and TM57 anti-tank mines at the depths mentioned. The system can detect and mark minimum metal mines (i.e. containing at least eight grams of metal) at depths of up to 200-mm.
