Arctic radar to probe 'space weather'

BBC News reports on the EISCAT-3D radar project to be built by UK,
China, Japan and Northern European countries

The radar, to be built across Norway, Sweden and Finland will operate
on 233 MHz and should come online in 2021.

EISCAT already operates radar facilities in the far north, but the new
technology is regarded as a big step forward in capability. "This is
the next generation," said Dr Andrew Kavanagh, a EISCAT member
scientist working with the British Antarctic Survey (BAS).

"The system will look like a flat field of antennas, much like some of
the big radio astronomy telescopes such as LOFAR and SKA. We will be
able to do a lot more with this new system - looking at large parts of
the sky simultaneously. A 3D view of the sky."

The new radar system will be set up at Skibotn in Norway, near Kiruna
in Sweden, and near Kaaresuvanto in Finland. Skibotn will have a
transmitter and receiver array, while the two other locations will
have receiver arrays.

The technology will enable scientists to probe in detail the
ionosphere - the region of the Earth's upper-atmosphere that ranges
from about 70 km to 1,000 km in altitude.
