Antidetection by radar device for a flattened superstructure of a ship

A device enabling a flattened superstructure carried by a deck of a ship to be rendered insusceptible to electromagnetic waves, in particular a superstructure of an idle battery of missiles onboard said ship and said missiles of which are contained in vertical shafts disposed partially under the deck of said ship and occluded at their upper part by swiveling doors which, in a closed position, constitute said superstructure at least in part, said device comprising:

• at least on each of the port and starboard sides of said superstructure at least one inclined plane screen able to reflect an incident beam of electromagnetic waves in a different direction from that of said incident beam, said screens projecting with respect to said deck by a height greater than a height of said superstructure and an inclination of said screens being such that they get closer to said superstructure as they get further from said deck, and
• a net reflecting the electromagnetic waves and stretched above said superstructure.
