Decameter coherent radars

RADAR NETWORK

At the end of 2014 with the support of RSF ISTP SB RAS began work on the deployment of decameter coherent radar in p.Stekolny (Magadan region). Purchased masts and cable system, signed a contract for the manufacturing and delivery of antennas for phased radar array.

The main mode of operation of decameter coherent radar is to monitor the characteristics of small-scale (decameter) inhomogeneities in the F-layer of the ionosphere in order to study the laws of their movement. Within existing models of such irregularities their movement is associated with the structure of the electric and magnetic fields at the point of scattering and allows to estimate the direction and the absolute value of the electric field over a wide range of distances and azimuths. Knowledge of the structure of the electric field in a wide range of longitudes and latitudes allows one to investigate the processes of convection in the ionosphere and study the dynamics of the ionosphere-magnetosphere system and its response to natural and human-made disturbances.

Currently, a large number of similar radars exists, united by similar structure, similar equipment and similar software. Such a network of radars is known as SuperDARN (Super Dual Auroral Radar Network, SD). There are currently 24 active radars in the Northern Hemisphere and 11 in the South Hemisphere. SuperDARN is an international project in which actively participate 12 countries: Iceland, Canada, Finland, France, Italy, Japan, UK, Australia, USA, South Africa, New Zealand and China. Each radar is funded by separate research agency or combination of agencies.

Until 2012, there was no such radars at the territory of the Russian Federation. At the end of 2012 under the financial support of the Russian Academy of Sciences and RosHydroMet in Arti (Sverdlovsk region) ISTP SB RAS together with IG UrB RAS assembled and launched into trial operation the first Russian radar of this type. Now the radar operates in a continuous mode, providing a continuous observations of about 96-98% of the time with a spatial resolution of 45 km, and the time resolution 1-2 minutes, in 50 degree field of view over the azimuth and 3500km over the range. Detailed information on radar is available on the website http://sdrus.iszf.irk.ru

The deployment of the radar in Stekolny (Magadan region), scheduled for 2015, will expand the area of longitudes that are available for the study by backscattering of HF radio waves, and for the first time to start monitoring full vector of ionospheric velocity in the polar region from the Russian Federation territory. In the future this allows to build and improve the systems for monitoring and forecasting the ionospheric conditions in the polar regions.
