- Shtora
Shtora ( _ru. Штора, ‘curtain’) is a
Russia n electro-optical active protection suite for tanks, designed to disrupt thelaser target designation andrangefinder s of incominganti-tank guided missile s (ATGMs).The system is mounted on the Russian
T-80 andT-90 seriestank s, the UkrainianT-84 , and the SerbianM-84 AB1] .Shtora-1 is an electro-optical
jammer that jams the enemy's semiautomatic command to line of sight (SACLOS ) antitank guided missiles, laser rangefinders and target designators. Shtora-1 is actually a soft-kill, or passive-countermeasure system. It is most effective when used together with a hard-kill system such as the Arena active countermeasures system. The system was shown fitted to a Russianmain battle tank during the International Defense Exposition, held inAbu Dhabi in 1995. The first known application of the system is the RussianT-90 main battle tank, which entered service in the Russian Army in 1993.The Shtora-1 system comprises four key components, the electro-optical interface station, which includes a
jammer ,modulator , and control panel, a bank of forward-firing grenade dischargers mounted on either side of the turret, which are capable of firing grenades dispensing an aerosol screen, alaser warning system with precision and coarse heads, and a control system comprising control panel,microprocessor , and manual screen-laying panel. This processes the information from thesensor s and activates the aerosol screen-laying system. Twoinfrared lights, one on each side of the main gun, continuously emit coded pulsed-infrared jamming when an incoming ATGM has been detected. Shtora-1 has a field of view of 360 degrees horizontally and –5 to +25 degrees in elevation. It contains twelve aerosol screen launchers and weighs 400 kg. The screening aerosol takes less than three seconds to form and lasts about twenty seconds. The screen-laying range is from 50 to 70 meters. It is also believed that the Shtora system can also locate the point where the threat originated from and plot afiring solution for the main gun, so that the tank crew can return fire.
