The USSI system demonstrated the feasibility of using a very low cost fiber optic underwater sonar array
to provide automated tripwire and ROI alarms in a harbor environment without operator intervention.
Among their topics are a new method of locating license plates based on the multi-threshold quantization segmentation of color images, a telemetry system for acquiring and processing neuronal signals, the impact of reward programs on customer behavior at commercial banks, a new data transmission protocol in delay tolerant mobile wireless sensors, remote diagnosis in traditional Chinese medicine using wireless sensor networks, simulating the response of multi-path directional interferences on a sonar array
, robust image watermarking using independent component analysis, analyzing and implementing power supply capacity based on multi-data acquisition, nonverbal emotion interaction of virtual characters in cartoon games, and emergency document structuring.
In the latest case this month, a Chinese submarine damaged an underwater sonar array
towed by a U.S.
In the latest incident earlier this month, a Chinese submarine damaged a sonar array
being towed by a US destroyer.
The latest incident saw a Chinese submarine damage an underwater sonar array
towed by the US destroyer USS John S.
The SQS-53C sonar array
is part of the AN/SQQ-89 undersea warfare combat system.
The US Navy has released its Final Environmental Impact Statement (FEIS) for its proposed Low Frequency Active (LFA) sonar array
The LFA would use underwater speakers to detect "enemy" submarines by blasting the world's oceans with powerful 220-decibel (dB) low-frequency sound waves.
To improve detection of the new breed of quieter submarine, the Navy hopes to employ a low-frequency active sonar array
. As opposed to passive sonar, which simply listens for unnatural sounds, active sonar produces a low-frequency signal (between 75 and 1,000 Hz) to create echoes off of hostile submarines.
The Underwater Warfare Suite Upgrade (UWSU) project will upgrade or replace a range of sensing capabilities, including a new passive towed sonar array
; a sonobuoy processing system; an upgrade to the existing hull-mounted sonar; and an active intercept sonar for torpedo defence.
Beijing, June 15 (ANI): Chinese military experts have claimed that the collision which took place between a Chinese submarine and an underwater sonar array
towed by a US warship in the South China Sea, could have been due to misjudgment of distance.
