This radar of the first generation of mobile radar systems in
World War II was in the Allied invasion of Normandy in use. In Switzerland, the system was never used in the tactical way. It was used for determining the locations of the first Swiss airspace control system the
SRF Airspace monitoring and management system. The LGR-1 radar was tested at various locations, including at the military airfield Dübendorf, at the Bütschelegg above Bern-Belp, at the Weisfluhgipfel (
Weissfluhjoch) and at the
Creux du Van. As weatherprotection a wooden hut was built around the LGR-1. The transportable in 10 loads lightweight radar LGR-1 was developed during the Second World War by
Bell Labs and
Western Electric and built by
Bendix Corporation in large numbers . ==Specifications==
