EISCAT’s UHF radar is a tristatic system, which currently has a central frequency of 929.5 MHz. It comprises a transmitter at Tromso in Norway and additional passive receivers at Kiruna in Sweden and Sodankyla in Finland. The antennas and receiver hardware at all three sites are basically identical, although of course the transmitter is unique to Tromso. The receivers are also essentially the same as those used for the VHF radar. The UHF system has been operating since 1981, although in that time it has undergone major upgrades of the transmitter and receiver hardware, as well as extensive development of its experimental capabilities.
