Product Description
The AQS-18A dipping sonar system represents the next stage in
evolutionary development, and the state-of-the-art in mid-frequency
dipping sonar performance. The proven high performance AQS-18A
components: dome control, reeling machine, and transducer have
been interfaced to a powerful digital processor, control unit,
and display.
Applications
The advanced processing brings greater performance by virtue of high
resolution digital processing, greater target contact memory space,
and the flexibility to increase the number of sonar beams, type and
length of pulses, and menu of operator displays.
The AQS-18A offers additional 1.6, 3.2, and 4 second pulse lengths.
The longer pulses put more energy on the target, and provide higher
Doppler resolution for maximum performance in highly reverberant
shallow water conditions. An FM mode is available for extremely low
Doppler target detection and maximum range resolution.
Key Benefits and Features
The total ASW system improvement of the AQS-18A system is 14 dB
over current systems and can provide more than two times the area
search rate of the AQS-18.
The 18A has reserve processing power and space for additional
processing features such as computer aided detection and classification,
multi-sensor target fusion, embedded training, and performance prediction
based on environmental data collected during past or current missions.
Built-in 1553 data bus protocol facilitates integration with aircraft
subsystems and components. Built-in-test (BIT) eases support and boosts
availability. The new processing weapon replaceable assemblies (WRA's) of
the AQS-18A have a significantly higher mean-time-between-failures
(MTBF) than current systems.
The AQS-18A sonars are in production and have been delivered to four nations.
