The Type 277 was a British
naval sea search radar equipped with a PPI display. The RAF adapted it
as the Type 52 radar for coastal defense. It had a full parabolic
antenna that reduced sea return considerably and also gave it altitude
finding capability. It could also be used for fighter direction and fire control.
