100% band occupancy
- 40GHz/s, @25kHz
(V/UHF), 100% band occupancy
- To accommodate
operational speed for multi wide band clients
- Effective detecting and
tracking of small duration signals
- Enables multi client
connection and maintain high POD
- Single-capture DF from
40s
- DF on frequency agile
signals with Built-in Fixed Frequency, Frequency
Hopping and Burst
- Signal Detection in LPI Mode
|
| High DF Accuracy |
- Accurate direction
finding using correlative algorithms
(interferometric or Watson-Watt) up to 9 antenna
array
- Remote narrow band DF
tasking (to/from other stations)
- Cumulative display of
Angles-of-Arrival using histograms
- Optional narrow band receiver for demodulating active signals of interest.
|
| High Sensitivity |
- Various Antenna
configurations available to optimize DF
sensitivity
- Variable sensitivity and selectivity by coherent integration and polyphase filtering
|
| Low Probability of Intercept (LPI) |
- Automatic detection of
Multiple fixed frequency emitters, frequency
hoppers and burst signals.
- Provide signal information - Start/Stop freq., Dwell Time, Azimuth and Time of signal event
|
| Time Synchronization |
- Effective time synchronization and distribution to all clients, derived from GPS time for baseline operations
|
| Tasking and Analysis |
- System can function in
a stand-alone environment where the DF operator
can create his own missions and tasks.
- System can function in
a larger system environment where the tasking is
done from remote positions.
- Mission data is stored locally in a database for later analysis and/or playback.
