Direction Finder for Special Use
The diversification of wireless telecommunications in these days causes negative
aspects of the interference against the public wireless communication and broadcasting.
Furthermore, an unlicensed radio signal disturbs the wireless communication of the Police,
security service and the emergency activity.
-
Example of the system
-
Typical system consists of the Center Station and Sensor Stations.
The Center Station controls the functions of the Senter Stations.
(ie. Radio Monitoring, Direction Finding and etc.)
The Sensor Stations set the receiving functions and measure bearing of received signal.
The measured data of bearing and frequency is sent back to the Center Station.
The Monitor in the Center Station displays bearing line on depicted map to process data received from the Sensor Station.
