It operates in the microwave range (5.7 GHz) where the processes occurring in the solar corona are accessible to observation over the entire solar disk. It is a crossed interferometer, consisting of two arrays of 128x128 parabolic antennas 2.5 meters in diameter each, spaced equidistantly at 4.9 meters and oriented in the E-W and N-S directions. It is located in a wooded valley separating two mountain ridges of the Eastern Sayan Mountains and Khamar-Daban, 220 km from Irkutsk, Russia.{{cite web|url=http://en.iszf.irk.ru/The_Siberian_Solar_Radio_Telescope|title=The Siberian Solar Radio Telescope – ISTP SB RAS|website=en.iszf.irk.ru|access-date=2 June 2019}}
