PROCESS AND SYSTEM FOR DETECTING HAZARDOUS ABANDONED OBJECTS

摘要

A process and system are disclosed for detecting in particular metallic objects in large-surface search areas (I) and may be advantageously used in particular for detecting abandoned hazardous objects. The process, that allows shape, size, orientation, depth and type of material of the search objects to be identified, uses at least one search signal-generating search probe (eddy current probe (15) and/or magnetic field probe) that is moved in relation to the search area (1), preferably in a substantially parallel direction to its surface, along a search path located on a search surface. At least one evaluation unit (20) connected to the search probe so as to receive is signals automatically allocates the search signals to positions of the search probe on the search surface determined by localisation means (4 to 7) and converts the signals into an image of the objects in the search area. The image may for example be a map of the location of the searched objects.
