Radar Reflector Buoys — SC DNR Offshore Reef Markers
Multiplastics needed radar reflectors for their marine buoys — deployed by SC DNR as offshore reef markers along the South Carolina coast.
The reflector had to fit inside a protective cone housing, extend down into the buoy cylinder to prevent damage, survive saltwater conditions, and actually work.
No drawings. No existing design. Just a problem that needed solving.

We researched radar reflector geometry and used AI-assisted calculations to optimize reflectivity across all angles. The reflectors were fabricated in aluminum to those precise specifications and designed to flat-pack for efficient shipping and field assembly.

The aluminum radar reflector alongside the protective cone housing it fits inside. The geometry had to be precise enough to reflect radar effectively while fitting within the physical constraints of the buoy assembly.

The reflector installed inside the buoy body — tucked under the protective yellow cone cap to prevent damage from wave action and vessel tie-offs. Invisible from the outside, working from the inside.

SC DNR deployed the buoys offshore on their reef marker program. Field testing confirmed radar returns clearly at 3 miles — from a buoy only 5 feet above the waterline.
