Real Time 3D Sonar technology for commercial and security applications

摘要

Using phased array technology, over 16,000 beams simultaneously are generated to produce an instantaneous three-dimensional sonar image of both moving and stationary objects. Capable of up to 12 updates per second, the co-registered 3D imagery from each ping allows visualization of the whole scene in real time. The 3D aspect enables the high resolution visualization to be performed from multiple perspectives. The addition of motion sensor inputs enables the data to be positioned accurately in 3D space and adjacent pings can be used to create mosaics on-line. The resulting whole area visualization allows for extremely rapid reconnaissance and inspection. The compact system is suitable for vessels and platforms of all sizes, including ROV, AUV, pole mount, and fixed installation. The integrated design allows for rapid deployment, and provides accurate information even in turbid water or inclement weather.
