OVERVIEW: The SQUARE PAIR aka 5N62 radar is a land based, long-range, 2-D, tracking and illumination radar operating in the H-Band (NATO)(IEEE: C-band).  

DETAILS:    The SQUARE PAIR radar is an illumination radar for semi-active target tracking with separate antennas for transmitting, receiving and for transmitting missile commands.  The larger parabolic section antenna is for the transmit path, the smaller parabolic section antenna for the receive path, with the dividing blade, termed a “knife”,  employed to avoid spillover. A  boom mounted circular polarized helical antenna on the side of the cluster is for the 5V21/5V28 missile uplink/downlink channel. Due to the technical limitations of a continuous wave radar, the missile guidance radar could only engage a single target at a time.  

It uses two modes of operation: unmodulated continuous wave with an evaluation of the Doppler frequency of the target and bi-phase coded modulated continuous wave  for measuring the target’s range.

 The SQUARE PAIR is associated with the S-200V aka  SA-5 GAMMON SAM. Each missile battalion has one P-35M (NATO designation BARLOCK-B) E/F-band 320 km range target search and acquisition radar with an integral D-band IFF system, one H-band NATO designation Square Pair 270 km range missile guidance radar, and six trainable semi-fixed single rail launchers. Initial detection of targets was conducted by a P-14/5N84A (NATO: Tall King C) A band early warning radar, operating in the 150–170 MHz range, with a PRV-17 (NATO: Odd Group) height finding radar to determine the target's altitude.
