Advanced Electromagnetic Chaff
Airborne expendable countermeasures are bursts of particulates ejected into the air as a countermeasure against missiles using RF/mwave or IR to seek their targets. Common RF countermeasures, usually referred to as chaff, are cartridges containing millions of short aluminized fibers. These fibers operate as dipoles, scattering radar signals in manners very similar to how chaff developed during WWII functioned.
With the changing and evolving threat landscape, the U.S. Navy’s Advanced Tactical Aircraft Protection Systems Program Office (PMA-272) seeks to develop improved countermeasure methods that extend the ability of the current and future aircraft to deploy effective self-defense. Understanding and engineering modern chaff systems are tasks SensorMetrix has undertaken to improve the capabilities of U.S. airborne warfighters.
