Air traffic control
In air traffic control applications, the R&S®DDF04E is
typically deployed at mid-sized or large airports for taking
the bearings of air traffic control communications. With
the R&S®DDF04E-4C option, the R&S®DDF04E can be expanded to support the required number of frequency channels. Even large airports with up to 32 frequency channels can be equipped in this manner. Along with the traffic control frequency channels, multiple distress frequencies can be permanently monitored and bearings can be taken when activity is detected.
Another key advantage of the R&S®DDF04E is its readiness to meet future air traffic control requirements. The forthcoming 8.33 kHz channel spacing for digital aeronautical radio is already integrated. In addition, the frequencies of the channels being monitored can be changed via mouse click. The number of channels being monitored can be increased by enabling the corresponding software (additional hardware may be required for ground transmitter suppression).
To mask emissions from the air traffic control's own
radiocommunications system, the R&S®DDF04E can
suppress ground transmitter signals by blocking selective
channels (see block diagram below).
