MAARSY
MAARSY (Middle Atmosphere Alomar Radar System) is an MST-Radar operating in the VHF range which was installed in Andenes, Norway (69°17'54.1" N 16°02'29.0" E) around 2010. It replaced the Alwin radar that existed there until then.
The radar antenna consists of 433 Yagi-antennas, as radiators, each with three elements distributed on a dodecagonal area of 6 300 m² with a triangular pattern. The radiators are each cross-interleaved to realize two different polarization planes. Their bandwidth is 5 MHz.
Each individual antenna is connected to its own transceiver with independent phase control and a scalable output up to 2 kW.
The signal shape of the transmitted signal is either rectangular, Gaussian or trapezoidal. The radar can transmit either with an unmodulated short pulse or phase-coded with a complementary or a Barker code.
