Abstract : The design of five classes of buoys adopted in 1952 provided for the use of an integrally constructed radar reflector of the triplane, or corner type. After several tests in ice it was found that the radar reflectors were severely damaged by the tendency of the ice to hang up under the horizontal planes of the reflectors when the buoy is inclined by the action of current. Accordingly, it was proposed to omit the horizontal planes from the reflectors. This test was intended to ascertain the effects of the omission of the horizontal planes of the radar reflector when a buoy is inclined toward or away from the observing radar vessel. As a result of the tests which were performed, it appears that (1) the horizontal planes in the 1952 type radar reflectors mounted on unlighted buoys perform an important function and (2) they should not be removed because of exposure to ice damage. Rather, they should be retained and some method of protecting the horizontal planes from ice damage should be devised.
