Project 1134 Kresta - Electronics
The ships were equipped with two quite sophisticated [for its time] radars - radar detection of total MP-500 "Cleaver", and air surveillance radar MR-310 "Angara" which issued the original data targeting for SAM "Wave".
Circular scan radar MR-500 "Cleaver" (AP was placed over the chimney), worked in the DM range (25-50 cm) on four fixed frequencies. Detection range air targets should not exceed 350 km (actually 270 - 300 km), surface - 50 km. The main disadvantages of MP-500 was the lack of data output in elevation (height), manual restructuring of the carrier frequency and great energy potential, which provides greater range, but at the same time leads to greater detection range by means of electronic intelligence of the enemy. Three-axis circular scan radar MR-310 "Angara" (AP placed at the top of the foremast). Detection range VC reached 150 km, and the NC - not more than 45 km. Power both radar was 1.5 - 2MW with a dead zone of detection of about 5 cables.
The project received one ship navigation radar "Volga" was later added more and radar "Don" with the prefix "Palm." In «Admiral Zozulya" during medium repair and modernization was installed radar targeting aviation "Vaigach".
For detection and bearing on the work of the enemy radars were installed at two stations signals intelligence MCI-11-12, 13-14 and MCI-station electronic intelligence MCI-15-16 "Gulf." To create a jammer uses two radar MP-150. On the superstructure deck, the board, aft of the bow PU-102 mill were two PU shoots clutter ZIF-121 (PC-2).
The ships were the primary data processing equipment and combat information post (BIP) - "Tablet-1134". For the exchange of information between the ships of Task Force on ships Project. 1134 using mechanical computing system IDP-200 "Sea-U"
The firing radar "Bean-1134" was intended for the guidance of missiles R-35 (PS - on the front of the foremast). For the issuance of the CO complex P-35 aircraft from ships established system of "success-have."
Electromagnetic compatibility of radars operating systems was provided by "asterisk-M-1134". Ships of Project 1134 were equipped with one set of equipment display system near surface situation MT-45H multi unstabilized posts.
The availability of SAS "Titan-2" for the "Berkut" was delayed. But the solution was found: the ships were armed with SAS "Titan" and "Vychegda" developed simultaneously as sonar weaponry, and was mastered by industry. Search SAS SAS Omnidirection MG-312M (ii) "Titan" (range target detection mode - 10 km) performed the task of detecting underwater targets, and data output purpose firing CEO of MG-311 "Vychegda" (detection range of - 3500 m) . Additionally, ASG "Titan" was intended to detect minefields and individual anchor mines and using SAS "Vychegda" became possible to measure the depth of immersion objective. The required range of detection and tracking of targets running at higher speeds is ensured by a large antenna size and high power generators. Under favorable hydrological conditions it could detect submarine submerged at ranges of up to 8 km and up to 18 km, and sea anchor mines and torpedoes at distances up to 2-3 km.
The ship had the contact station for submarine detection by heat signature MK-110K and the station submarine detection of infrared radiation of the water surface MI-110P. During service station the ships failed to meet expectations of developers because of the low efficiency and the numerous false positives. For these reasons, in order to detect submarines it was practically not used.
