+ | Direction finding systems were used for various purposes. | ||
+ | |||
+ | On the one hand, the [[Monitoring service]] used direction finding to detect suspicious foreign signals, in WWII especially those operating in Germany, or signals from within the country which could originate from spy radio stations. Near-field direction finding was carried out after a rough localisation of the transmission with direction finding vehicles, which could approach a suspicious transmitter site as inconspicuously as possible in the neighbourhood. Direction finding receivers carried inconspicuously by the defence signalmen could then be used to determine the location between or within individual buildings. | ||
+ | |||
+ | On the other hand, direction finding was used by the air force to localise aircraft, they were used in permanent installations and at military airfields, where direction finders were mounted in vehicles. | ||
