The main outdoor facility is a test lane of 80m by 5.4m soil area, equipped with two aluminium gantries running on a rail system. Each gantry can take loads of up to about 200kg and each is fitted with a 2m´ 5.5m computer-controlled x-y positioner, covering the full width of the lane to 1mm resolution. One gantry may be hauled along the entire lane using a motor (speed 1 m/s typical). External users are able to mount their sensor systems on the scanning frame (loads of up to 15-30kg) and test the capability for detecting targets in the test lane. The test lane is also suitable for the evaluation of hand-held detection instruments.
A reference plot near the centre of the lane has a sliding tent cover and is separated in the ground by a heavy gauge PVC liner with drainage.
A length of about 50m of the test lane is currently configured with 236 test targets buried in 7 soil types (see below).
Monitoring sensors are installed for soil temperature and moisture, air temperature and humidity, rainfall, wind speed, wind direction and solar radiation.
Beside the test lane there is an open area, offering the possibility of testing vehicle-mounted mine detection systems.
