Side-scan sonar is a proven tool for detection of underwater objects, particularly those objects that project above the seafloor. Rapid assessment of side-scan imagery for object detection is critical for port security needs. However, current side-scan data processing techniques are largely manual,...

In our view, this is unacceptable, as it can significantly affect the quality of sonar images and the subsequent target detection accuracy. Kapetanovic et al. (2018) proposed a data-driven CPP method in which the AUV replanned the search path based on the detection results of the SSS, redu...

DETECTION algorithmsCOMPUTER performanceSONARNOISECOMPUTATIONAL complexityAs seabed exploration activities increase, side-scan sonar (SSS) is being used more widely. However, distortion and noise during the acoustic pulse's travel through water can blur target details and cause feature loss in images, ...

By the laws of physics, sonar waves reflected from a target have different radiuses depending on the distance of the target. When the operator focuses on 25 meters, the 5900 software delays each sound sample to adapt to the corresponding radius. At 75 meters the radius is larger etc. The ...
Doppler shifts representing the target speed is measured by use of narrow band transmitted signals. The dipping sonar is the primary undersea warfare sensor of helicopters. It enables the helicopters to accomplish missions of submarine detection, tracking, localization, and classification by simply “...
