Latest improvements for the echo sounding system of the Italian radar glaciological group and measurements in Antarctica
radioglaciology ground penetrating radar ice thickness measurements
2015/10/8
Radio echo sounding is an active remote-sensing method using electromagnetic wave penetration in a particular medium such as ice and permits the measurements of its thickness, the level of the bedrock...
