The AN/AQS-13F is the US Navy’s
best inner zone ASW sensor.
The long-range, active scanning sonar detects and maintains
contact with underwater targets through a transducer
lowered
into the water from a hovering helicopter. The system
provides
target classification clues and can accurately determine
opening
or closing rates of moving targets. Active echo-ranging
determines the target’s range and bearing.
The AN/AQS-13F
has been designed to provide rapid tactical
response against the most advanced submarine threats.
High-speed
reeling allows a dip cycled to maximum depth to be
completed within
3.5 minutes, while the azimuth
and range
indicator and receiver provide a video display for
the operator.
The system’s
Sonar Data Computer (SDC) uses digital
processor techniques. This enhances detection capabilities
in
shallow water and reverberation-limited conditions
while
essentially eliminating false alarms from the video
display. The
higher energy transmitted with the longer pulse SDC
mode,
combined with the narrowband analysis, substantially
improves
the figure of merit in non-reverberant conditions more
typical
of deep water operation as well. |
