When measuring with ground radar, it is possible to obtain continuous data on the thickness of the ice. Measuring the thickness of the ice makes it possible to conduct a preliminary investigation of the ice before opening the ice route. In this case, the ground radar measures the wider corridor between the edges of the investigated corridor along a zig-zag profile line. By measuring in this way, areas with greater and thinner ice thickness are distinguished in the investigated corridor. It is also possible to check the thickness of the already established ice road and identify potential areas of thinner ice.
