Synthetic Aperture Sonar (SAS) is a revolutionary seafloor mapping technique that provides ultra-high-resolution imagery at the seabed at superior coverage rates. Kraken Robotic Systems Inc. (Kraken) is a marine technology company that develops and markets advanced sonar sensors, including SAS, for military and commercial applications. The company's primary market for their SAS technology (~70% sales) is military and defense customers, where the ultra-high-resolution imagery is used for underwater object detection and mapping. Kraken wish to expand its civilian customer base to match or exceed that of its military clients. To achieve this goal, there is a need to demonstrate the technology for other, untested applications (e.g., geological, engineering or habitat mapping applications) in expanded customer sectors for Kraken (e.g., fisheries, aquaculture, marine construction, and ocean energy sectors). Kraken and the NSCC Applied Oceans Research Group (AORG) will work together to conduct proof-of-concept tests of the technology in these other areas of application. Surveys will be conducted in the vicinity of Halifax Harbour, offering a variety of seafloor types over which to test the technology. The data will be collected using the Kraken KATFISH actively-controlled towed vehicle fitted with the SAS system. The seafloor SAS data will be ground-validated by NSCC using an underwater ultra-high definition video system developed at NSCC and mounted on a drop camera frame. These data will then be processed using data integration techniques to test the utility of the SAS data for generating seafloor habitat and surficial sediment maps. The result of these research activities will offer short to medium term benefits to Kraken through demonstration of the advantages of SAS for non-military application. The collaboration will also advance the general field of seafloor habitat mapping, testing the latest ocean floor mapping technology. ******

合成孔径声纳(SAS)是一种革命性的海底测绘技术，它在海床上以卓越的覆盖率提供超高分辨率的图像。克拉肯机器人系统公司(Kraken)是一家海洋技术公司，开发和销售先进的声纳传感器，包括用于军事和商业应用的SAS。该公司的SAS技术的主要市场(约70%的销售额)是军事和国防客户，在这些客户中，超高分辨率图像用于水下目标探测和地图绘制。Kraken希望扩大其民用客户基础，以赶上或超过其军事客户。为了实现这一目标，需要在扩大的客户部门(如渔业、水产养殖、海洋建筑和海洋能源部门)中展示该技术用于其他未经测试的应用(如地质、工程或生境测绘应用)。Kraken和NSCC应用海洋研究小组(AORG)将合作在这些其他应用领域对该技术进行概念验证测试。将在哈利法克斯港附近进行勘测，提供各种海底类型以测试该技术。这些数据将使用安装了SAS系统的Kraken katfish主动控制拖车收集。NSCC将使用NSCC开发的水下超高清视频系统对海底SAS数据进行地面验证，该系统安装在一个降落式相机框架上。然后，将使用数据整合技术对这些数据进行处理，以测试SAS数据在生成海底生境和表面沉积物地图方面的效用。这些研究活动的结果将通过展示SAS在非军事应用方面的优势，为Kraken提供短期到中期的好处。合作还将推进海底栖息地测绘的一般领域，测试最新的海底测绘技术。******
