|Since 2005, Vallon also offers a Dual Sensor Detector, the Minehound™*. This innovative advanced technology detector combines a leading-edge ground penetrating radar (GPR) with a high-performance metal detector (MD). The unit has been designed specifically for use in the most challenging humanitarian demining operations and provides significant improvements in the efficiency of clearance.
The MINEHOUND™, VMR2 is simple to use and provides the operator with clear audio signals to alert the presence of a potential mine threat. When a threat is located, the MD audio provides accurate position information and mass of metal indication. The GPR audio then provides additional position and depth information, and gauges the radar cross-section of the target. Both detectors can be used separately or together. The GPR responds to even the smallest flush buried mine (diameter > 5 cm), but not to smaller metal fragments. This means that metallic clutter such as bullet casings, small arms rounds and shrapnel, which commonly causes false alarms, is rejected by the system.
The GPR also detects zero or minimum metal mines which are normally difficult to locate using metal detection techniques alone.
The MINEHOUND™ VMR2 uses a MD produced by Vallon GmbH (VMH3) and a custom designed 1GHz GPR designed by ERA Technology. The GPR is a time-domain radar transmitting 1 ns duration impulses at a repetition frequency of 1 MHz. A dedicated state-of-the-art DSP processor is used to provide all control and signal processing function
