Abstract (en)

The radar deflector for a marine vessel has a frusto-conical casing attached to the superstructure of the vessel to reflect the radar waves. The lower edge of the casing (6) has a gusset (7). The angled surfaces of the casing reflect the radar waves in a different direction from the incident angle. The height of the casing and gusset is less than the length of the missile well doors which they cover.
