Check out an earlier Russian system
A more complete hemispheric protection is the Russian Arena E
developed by the Russian company KBM. The system is designed to
protect the tank from attacks of anti-tank guided missiles launched
from the ground and by attack helicopter and lightweight anti-tank
grenades (such as RPG). The system weighs between 1 1.3 tons
(depending on the coverage and configuration) and uses a fixed,
omni-directional radar, that covers a sector of 220 290 degrees
around the tank. The protective charges are housed in a "belt" of
22-26 protective charges (depending on the turret size and shape),
each positioned to cover a specific sector. Once an incoming threat
is detected by the radar, the system ejects a charge above and
sideways from the tank, to a position best suited for intercepting
the target. As the charge explodes, it throws a deadly hail of
fragments downward, to shutter and destroy the incoming projectile.
The system is capable of engaging incoming missiles, at speeds
ranging from 70 to 700 meters per second. The system creates a
virtual "cone" shaped shield at a radius of 20-30 meters from the
tank, and its response time, from target detection to destruction
is 0.07 seconds. When the system is triggered, a warning signal is
activated, to warn infantrymen that may be following the tank to
open some distance or take cover. The status of the Arena E system
is unclear, although the system was seen in public since the mid
1990s, it is believed that funding problems delayed final
development and deployment of the system.
While Arena-E provides an effective protection against many types
of anti-tank threats, from RPGs to fast missiles such as Hellfire
and TOW, it cannot defeat fast missiles (such as HVM) and tank
projectiles, such as HEAT shaped charge projectiles and APFSDS
penetrators. Different countermeasures are being examined to defeat
these threats, including the deployment of steel bars, which are
accelerated into the projected flight path of the incoming
projectile. The kinetic energy discharged from the collision
between the steel bar and the projectile can disintegrate or
destabilize the projectile, shift it from its course, or cause it
to hit the target at angles that do not facilitate effective
penetration.
