ADROS-KT-01AVE Electronic-optical countermeasure system

The ADROS-KT-01AVE optical-electronic countermeasure system is intended for active protection of helicopters against missiles with infrared guidance units. The mass of the existing countermeasure systems are known to be primarily designed to counter missile guidance units that use amplitude-phase modulation. To mislead the missile’s guidance unit, and, therefore, thwart missile attack against helicopter, electronic countermeasure signal generated by the system should be 1.5-2 times (sometimes even 20 times) stronger than the signal emitted by the object under protection.
The ADROS-KT-01AVE is efficacious against missiles integrating infrared homing heads with heightened noise immunity to other types of modulation: amplitude-phase modulation (APM) or pulse-position modulation (PPM). This enables lock-in failure in case of such guided missiles as Stinger (APM), “Igla” (PPM), “Igla-1” (APM), R-60 (APM), R-60M (APM), R-73 (PPM), Sidewinder (APM) and more.
The ADROS-KT-01AVE system, unlike equivalent systems developed in or outside Ukraine, does not require the intensity of electronic countermeasure signal to differ much from that emitted by helicopter engines. Operation of the system depends on a new electronic-optical countermeasure principle, and incorporates a newly-designed electronic-controlled modulator with programmable processors.
