|
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. Sensor-Info: aircraft:bt-67:emr_ice, 6794 |
