Shtora ((ロシア語:Штора), "curtain") is an electro-optical active protection system or suite for tanks, designed to disrupt the laser target designation and rangefinders of incoming anti-tank guided missiles (ATGMs). The system is mounted on the Russian T-80 and T-90 series tanks, the Ukrainian T-84 and the Serbian M-84AS. The existence of ''Shtora'' was revealed in 1980 by Adolf Tolkachev.〔''The Billion Dollar Spy: A True Story of Cold War Espionage and Betrayal'', David E. Hoffman, location 3142, Kindle edition.〕 Shtora-1 is an electro-optical jammer that disrupts semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser rangefinders and target designators. Shtora-1 is a soft-kill, or passive-countermeasure system. The system was shown fitted to a Russian main battle tank during the International Defense Exposition, held in Abu Dhabi in 1995. The first known application of the system is the Russian T-90 main battle tank, which entered service in the Russian Army in 1993. It is also available on the BMP-3M infantry fighting vehicle. ==Specifications== According to Steven Zaloga and ''Tankomaster'':〔 〕 *Laser illumination sensors : * *2x TShU-1-11 precision sensors and 2x TShU-1 rough sensors * *Field of view (each): -5° .. +25° elevation and 90° azimuth * *Field of view (total): 360° azimuth *EO interference emitters : * *2x OTShU-1-7 * *Operating band: 0.7 .. 2.7 mkm * *Protected sector: 4° elevation and 20° azimuth * *Energy consumption: 1 kW * *Light intensity: 20 mcad *Anti-FLIR smoke grenades : * *12x 81mm 3D17 * *Obscured band: 0.4 .. 14 mkm * *Bloom time: 3 sec * *Cloud persistence: 20 sec 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shtora」の詳細全文を読む スポンサード リンク
