PROBLEM TO BE SOLVED: To reduce irregular behavior due to the air flow, in a marine radar antenna.SOLUTION: In a marine radar antenna 1 where antenna configuration members, including a radiation waveguide and a radio wave shaping plate, are disposed in a radome 2 having a horizontally long cylindrical cross-section and disposed to extend in the horizontal direction, and provided with a horizontally long side plate 3 closing the openings at both ends of the radome 2, and disposed rotatably about the central part of the radome 2, the plate surface 31 of the side plate 3 is curved in the longitudinal direction to project outward, so that at least one of a force and moment acting by the air flow is reduced. |
