The 5N62V (Cyrillic: 5Н62В; NATO designation: Square Pair) is a missile guidance radar for the S-200V surface-to-air missile system (NATO designation: SA-5 Gammon).
The original version S-200A, code-named Angara (Cyrillic: «Ангара»), was developed since 1958 and had a range of up to 180 km. The follow-up version S-200V, codenamed Vega (Cyrillic: «Вега»), appeared from 1970 with a range of up to 240 km. From 1975, the S-200D version codenamed Dubna (Cyrillic: «Дубна») was available with a range of up to 300 km. This version is also reportedly capable of firing missiles with a nuclear warhead.
The radar is an illumination radar for semi-active target tracking with different antennas for transmitting, receiving and for transmitting missile commands. It uses two modes of operation: unmodulated continuous wave radar with an evaluation of the Doppler frequency of the target and bi-phase coded modulated continuous wave radar for measuring the target’s range. Due to the technical limitations of a continuous wave radar, the missile guidance radar could only engage a single target at a time.
The transmit power was generated by a K-89 type klystron. The transmit frequency is quartz stabilized and provided by a series of frequency multipliers. Unfortunately, no information about the transmitting frequency is published. However, based on the rating of the antennas (ratio of wavelength to antenna area and aperture angle), it may possibly be in the S-Band.
In the early 1980s, the Vega version was exported to other Warsaw Pact countries under the designation S-200VE (Cyrillic: «С-200ВЭ»).
