|
The EM-Bird EMR (Electromagnetic Reflection System) is a digital frequency-domain electromagnetic-induction (EM) system, dedicated for measurements of sea ice thicknessradar-based measurement system for the determination of ice thicknesses in Polar regions. The radar signal is a 150MHz burst with a signal length of 60ns or 600ns. The maximum performance is 1.6kW with a sensivity of 190dB. |

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 winchEMR system comprises transmitting and receiving antennas with a weight of 45 kg each. Furthermore a data aquisiton unit, a transmitting unit and an operator PC are installed in a rack. HF amplifiers are installed inside the wing compartments.
