In the early 1970s, the development of a new highly effective radar, the Daryal type, was commenced by the Mints Radiotechnical Institute (RTI) under the supervision of A. Mints and V. Ivantsov. The main distinguishing features of this radar are an extremely high radiated power, use of a phased array for both reception and transmission, and digital processing of signals. The transmitter antenna of the radar had dimensions of 30 x 40 meters. The antenna included many centrally controlled transmitters within it. The receiving antenna had dimensions of 80 x 80 meters. The radar worked in the meter bandwidth.
There were nine stations of this type in the former Soviet Union. The reduced version of the receiving station was successfully tested in the trans-polar area near Pechora. In 1984-1985, the nodes with the Daryal radars were placed on combat duty in the north (Olenegorsk) and in Azerbaijan (Mingechaur). In the mid-1980s, building of new Daryal-U and Volga radars began at the Dnepr radar positions in Latvia (Skrunde), Belarus (Baranovichi), Ukraine (Nikolaev), Kazakhstan (Balkhash), and Siberia (Irkutsk).
Construction of the new Yeniseysk-15 radar node started at Yeniseysk near Krasnoyarsk for the creation of an uninterrupted radar field on the external border of the USSR in the northeastern missile danger zones. The building of a new radar near Yeniseysk infringed on the ABM treaty, and was subsequently halted.
In accordance with the intergovernmental agreement, the obsolete Dnestr-M radar in Skrunda worked until 1998, and then it had to be dismantled within 18 months. The new Daryal radar built nearby was blown up on 04 May 1995.
