New decameter radiopolarimeter URAN-2
The description of the new decameter radiopolarimeter is submitted. It is created based on the phased array URAN-2, which is the greatest decameter array in the world after UTR-2, having the effective area about 30 000 m2, consisting of 512 broadband dipoles and working at frequencies from 10 up to...
