Draft:P37 radar

= P-37 "Bar Lock" = The P-37 “Metch” (1RL139, Cyrillic: 1РЛ139 «Меч» = “Sword”, NATO designation: “Bar Lock”) is a transportable radar developed in the soviet union. It is a 2D radar for air surveillance, fighter guidance, and target assignment for air defense missile systems.

During its very long service life, several versions of the P-37 were built. These ranged from the early days with an additional trailer 8, which mainly contained the tube-based SBZ system, to the most modern station, the so-called 90-version, which had the entire reception path transistorized and equipped with circuits (up to medium integration rate).

Estimates of the BAR LOCK's radiated power output, based largely upon photographic evidence, ranged as high as 5 megawatts peak pulse power from each of its 5 transmitters. With 5 megawatts in each beam the BAR LOCK would have had ten times the power of previous similar radars and would have significantly improved the detection and tracking capabilities of the Soviet air defense system.
