|
The EM-Bird is a digital frequency-domain electromagnetic-induction (EM) system, dedicated for measurements of sea ice thicknessFrequency Modulated Continuous Wave (FMCW) System operates in the frequency range 400-800 MHz. It shows the structure of the upper 100 m of ice masses with a vertical resolution in decimeter range. |
