Signal Analysis > Vehicle Based Radio DF System

 
Vehicle Based Radio Df system The Integrated COMINT Workstation (Vehicle Based Radio Df system) provides mobile signal detection, Demodulation, location and evaluation of VHF/UHF communication signals.

The system utilizes advanced Windows NT-based software with minimum hardware, comprising a single receiver and computer, plus a low profile, roof-top mount antenna, to achieve all system functions while on-the-move.

The system capabilities include Fast Scans on operator selected frequency ranges at specific step size. Signal environment presented via tabular display of frequency, bearing and status of intercepted signals.
The system is also equipped with Preset Frequency Scan which is same as continuous scan, but only scans specific operator designated frequencies, rather than ranges.
The basic application of Monitor/DF is provided using Single frequency mode which provides a line-of-bearing histogram display of all emitters on the selected frequency. Results are graphically displayed in a frequency-versus-bearing format with frequency presented on the vertical axis and bearing on the horizontal axis.
