Components and Specifications
The FMCW snow system comprises a transmitting and a receiving horn antenna. Two different antenna setups are available. A rackmount unit containing the electronics is installed close to the antennas. The installation also comprises an amplifier and a cooling unit. The system is operated from an external PC.
