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.
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.
