|
The EM-Bird is a digital frequency-domain electromagnetic-induction (EM) system, dedicated for measurements of sea ice thicknesssnow radar or ultra wideband microwave radar (UWB/M) is for mapping near surface internal layers with very fine resolution and measuring the thickness of snow over sea ice. The system is designed to operate in Frequency-Modulated and Continuous Wave (FMCW) mode for low-altitude measurements (500-1000 m) and stretch mode for high-altitude measurements 2500 m and above. |

Components and Specifications
The EM-Bird system comprises the EM-Bird itself, which is lowered to the ice during flight. For deployment a winch is installed inside the aircraft. Power supply unit and operator PC are located on the winch.
Specifications of the EM-Bird(without mounting)
...
UWB-M Snow Radar comprises a transmitting and a receiving horn antenna. Furthermore several rack units with a standard width of 480mm are required (see images and documentation). An 115 VAC / 60 Hz Uninterruptable Power Supply (UPS) ensures constant power supply to the system. The system excl. the rack itself and the UPS weights about 80 kg.
