EISCAT Remote VHF receivers

Description
The EISCAT Mainland radar system has remote receiver sites at Kiruna and Sodankylä. From 1981 to 2012 the remote receivers operated at the frequency of the fully steerable Tromsø UHF radar (930 MHz), enabling scanning tristatic measurements. Increasing interference from mobile telephony base stations in the 900 MHz band prevented further operation and the remote stations were converted to the EISCAT Tromsø VHF radar frequency (224 MHz) in 2012. This limits the use somewhat as the VHF antenna is fixed during operation and the system is soon to be replaced by EISCAT_3D.

isr- Description
- The remote receivers produce lag profile estimates from an overlap region between transmitter and receiver beams. Most important is the ability to measure the Doppler velocity component along the transmitter-receiver bisecting line, from which full three-dimensional velocity vectors can be calculated.
