The '''Wullenweber''' (the original name introduced by Dr. Hans Rindfleisch was Wullenwe'''v'''er) is a type of Circularly Disposed Antenna Array (CDAA) sometimes referred to as a Circularly Disposed Dipole Array (CDDA). It is a large circular [[antenna (radio)|antenna]] array used for [[radio direction finding]]. It was used by the military to [[Triangulation|triangulate]] radio signals for radio navigation, intelligence gathering and search and rescue. Because its huge circular reflecting screen looks like a circular fence, the antenna has been colloquially referred to as the ''elephant cage.'' The term ''wullenwever'' was the World War II German [[OfficialCode covername|cover term]] term used to identify their secret CDAA research and development program; its name is unrelated to any person involved in the program.
