Klein Heidelberg (KH)[2] was a passive radar system deployed by the Germans during World War II. It used the signals broadcast by the British Chain Home system as its transmitter, and a series of six stations along the western coast of continental Europe as passive receivers. In modern terminology, the system was a bistatic radar. Because the system sent no signals of its own, the allies were unaware of its presence, and did not learn of the system until well after the D-Day invasion.[3] The system is referred to as Klein Heidelberg Parasit (Small Heidelberg Parasite)[4] in some references.[5]
