9S15M

9S15M Obzor-3 (Cyrillic: «Обзор-3», NATO reporting designation: “Bill Board”) is operating in F-Band fully coherent 3D air surveillance and target acquisition radar for the S-300V (NATO reporting designation “SA-12”) surface-to-air missile system. When used exclusively as an tactical air surveillance radar, it was given the Russian designation 1RL140 (Cyrillic: "1РЛ140").

The radar uses an electrohydraulic rotating in azimuth and electronically scanning in elevation phased-array antenna. It consists of a large array of the primary antenna and a smaller array mounted below for IFF interrogation. The transmitter is fitted with a traveling wave tube. The transmitted pulse contains a linear frequency modulated waveform.

The radar is mounted on a single tracked vehicle that houses all the electronics, antennas, and power generators.

This radar is also used in Syria as p/o “SA-12” surface-to-air missile system.
