Radar information
Under development...
In addition to operating as a passive receiver system, KAIRA is also capable of receiving signals from nearby scientific radars. This page describes the relevant parameters.
PLEASE NOTE that KAIRA is an independent facility. Having allocated time on KAIRA does not imply the reciprocal allocation on any of these other facilities. Likewise, having time allocated on a radar facility does not guarantee time on KAIRA.
EISCAT VHF radar parameters
Because the KAIRA system is often used in conjunction with the EISCAT VHF radar at Ramfjordmoen, near Tromsø, the following information may also be useful.| Parameter | Value |
|---|---|
| VHF transmitter direction | 313.95 degrees |
| VHF transmitter frequencies | 222.8 – 225.4 MHz |
Depending on the exact radar experiment used, this will also affect which subbands are required with KAIRA.

MAARSY radar parameters
A second radar in the vicinity of KAIRA is MAARSY. Relevant parameters for this facility are as follows:
| Parameter | Value |
|---|---|
| MAARSY transmission frequency | 53.50 MHz |
| Required KAIRA RCU mode | 3 (w/ 200 MHz clock) |
| Longitude | 16.04 E |
| Latitude | 69.30 N |
| Equivalent KAIRA subbands | 273:275 |
MORRO radar parameters
Yet another radar in the vicinity of KAIRA is MORRO at Ramfjordmoen, Norway.
As far as we know, it is no longer (never was?) operating. As a result, plans
for KAIRA to monitor this radar have been dropped. The only parameters for this
failed facility we could glean were as follows:
| Parameter | Value |
|---|---|
| MORRO transmission frequency | 56.00 MHz |
| Required KAIRA RCU mode | 3 (w/ 200 MHz clock) |
| Equivalent KAIRA subbands | 284:289 |
EISCAT 3D radar parameters
The EISCAT 3D radar is a replacement for the existing EISCAT mainland facilities. It will operate at VHF frequencies, which fall into the range of frequencies that can be detected by KAIRA.
EISCAT 3D will have its transmitter located at Skibotn, Norway, which is not far from the KAIRA site. The remote stations of EISCAT 3D will be located at Karesuvanto, Bergfors, etc..
It is not clear whether EISCAT 3D will be operational within the lifetime of the KAIRA facility, but if so, then details of the transmission frequency and beam patterns will be posted here.
