Attention:
Operation of the EMR requires experienced personnel on board the aircraft.
Summary
The EMR (Electromagnetic Reflection System) is a radar-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.
