Stealthing bridges and buildings isn't something new and
from this little information it's hard to tell if the
suggested solution is something suitable for aircraft,
ships or vehicles.

Well if you can make the blades of a wind generator less visible to radar, then surely the same techniques could be applied (or have
already been applied) to reducing the Radar Cross-Section (RCS) of propellor-driven aircraft such has the Hercules or Osprey..?
