A SAMPLING OF AIRBORNE IR DECOYS AND DISPENSERS

摘要

This month JED will look at airborne infrared (IR) decoys and dispensers. IR decoys, also known as countermeasures flares, remain one of the simplest countermeasures for protecting rotary- and fixed-wing aircraft against IR-guided threats. This is due to their effectiveness against most types of fielded IR-guided missiles, as well as their affordability.IR decoys are composed of a pyrotechnic material, such as Magnesium Teflon (MT) or Magnesium Teflon Viton (MTV). These materials are mixed to provide an IR signature that closely approximates an aircraft's IR signature. These materials burn in air and when ejected from the platform have an almost instant rise time. The decoy's objective is to capture the missile seeker's tracking function and then cause the missile seeker to lose track of the platform.
