The P-35 (Russian: "Сатурн"; English: Saturn) also referred to by the NATO reporting name "Bar Lock" in the west is a 2D E band/F band[2] radar developed and operated by the former Soviet Union.

Development

The P-30 was developed by the All-Union Scientific Research Institute of Radio Engineering (VNIIRT)[3] as an early warning ground control and interception radar for the Soviet Air Defence Forces, airforce, and navy of the Soviet Union. Saturn was a development of an earlier radar design, the P-30 radar with which it shares many similarities. By 1958 the radar had completed state trials and was accepted into service, offering improved detection range and reliability than the previous P-30.[4]

In 1961 an improved variant of the P-35 was developed, the P-35M,[4] which featured an improved antenna layout. By 1971 a new variant of the P-35 had entered service, "sword-35". The sword-35 upgrade featured faster scanning and an improved antenna layout and polarization filters to help eliminate passive interference and improve detection of targets flying below 300 meters. Sword-35 also incorporated a limited capability to modulate pulse duration and frequency to counter active jamming.[4] The P-35 has now been succeeded by its successor, the P-37 radar.

Description

The P-35 is a semi-mobile radar composed of a trailer mounting the control cabin and antenna equipment, equipment being transported by truck. The antenna system of the P-35 is composed of two open frame truncated parabolic antenna accomplishing both transmission and reception, with both antenna are fed by a stacked beam composed of six feed horns. The radar uses two antenna with azimuth scanned mechanically, but unlike the previous P-30 both antenna are horizontal, the radar not using the V-beam system to determine target altitude. The right hand side of the upper antenna carried the antenna array of the IFF secondary radar, which was used to identify detected aircraft as friend or foe.

Operators

The P-35 was operated by the Soviet Union from 1958 and though they have since become obsolete, they were passed down to successor states after the fall of the Soviet Union. The radar has been exported and continues to serve in some areas around the world.
