Abstract
This paper presents the detection results of metallic guard wires covered/embedded in snow measured by an FM-CW radar. First, the brief principle of an FM-CW radar as well as its applica-tion to object mapping are explained, and then an FM-CW radar system is explored which is operative in the microwave L-band frequencies. The explored radar system was applied to the actual field measurement for the purpose of detecting metallic objects buried in snow. The radar system mounted on a van showed its potential ability in detecting and mapping the guard wires on road shoulders at least 50cm deep in snowpack in a real time operation, demonstrating its usefulness for monitoring snow shoveling actions.
