history
This radar of the first generation of mobile radar systems was in World War II when Allied invasion in Normandy in action. In Switzerland , the system was never used in tactical use. It was used to determine the locations of the first Swiss air surveillance system ( SFR air surveillance system ). The radar was tested at various locations, including the Dübendorf military airfield , the Bütschelegg above Bern-Belp and on the Weissfluh summit at Weissfluhjoch and the Creux du Van . A wooden barracks was built around the facility to provide weather protection.
The lightweight LGR-1 radar, which can be transported in ten individual parts, was developed by Bell Telephone Laboratories during the Second World War and built in large numbers by Western Electric and Bendix.
