CN-15 camouflage netting
From Wookieepedia, the Star Wars wiki.
Fabritech's CN-15 camouflage netting was formed of netting made up of metallic jamming fibers which produced a reflective ability that avoided detection from standard sensor sweeps. It needed to be connected to a small power source for maximum effectiveness. The net is covered in overlapping sensor baffle scales that emulate the emissions of the surrounding terrain.
It came in a small backpack and was deployable by 2 people in under a minute. Fully expanded, it would cover a 15 square meter area.
It was once tested underwater by the mercenary Gunman, and worked just as effectively, so long as the power cell lasted.
