US Army tests smokescreen that hides troops from radar and infrared

DEVCOM CBC demonstrated its Millimeter Wave Screening Obscuration Module at Aberdeen Proving Ground, mixing thousands of coated carbon fibers into smoke to scatter millimeter-wave radar beams. About 13.6 kg of fibers were dispersed, dropping target signatures below detection levels.

• The SOM module disperses about 30 lb (13.6 kg) of carbon fibers
• Fibers act as passive dipoles on military radar frequencies
• The smoke also blocks visual, night vision and IR sensors
• The system was transitioned to PME CBRND for fielding
