Attention:
Operation of the Ultra-Wideband Microwave Snow Radar requires experienced personnel on board the aircraft.
Summary
The snow 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 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.
Position
Horn antennas are installed in the underfloor of the aircraft. Electronics and data aquisition are installed in a rack in the cabin. |
