3D Sidescan developers team with Pacific Northwest sonar marketing specialists

Seattle – Ping DSP has named SUBSEA 20/20, Inc. the first authorized sales agency to represent their new line of 3D Sidescan sonar systems. After several years of research, product development and testing, Ping DSP recently introduced the first true 3D Sidescan. Ping DSP’s 3DSS sonar is based on patented Computed Angle-of-Arrival Transient Imaging (CAATI) technology which provides high resolution 3D point cloud images over the entire water-column including the seafloor, complex structures and mid-water targets. Unlike interferometric sidescan which resolves one blended angle-of-arrival at each range sample, CAATI resolves multiple simultaneous angles-of-arrival and separates seafloor returns from sea surface, water-column and multipath interference. The result is true 3D Sidescan and is ideally suited for a wide variety of underwater mapping and imaging applications including shallow water bathymetry, search and recovery, structure inspection, habitat mapping, and water-column target detection.

SUBSEA 20/20 principal, Eric Munday, recently completed technical training at Ping DSP factory headquarters in BC, Canada and, in cooperation with Ping DSP technicians, subsequently conducted field trials in Seattle’s Lake Union and Lake Washington. Using a Ping DSP 3DSS-DX-450, the team demonstrated the 3D imaging and bathymetric mapping capabilities of the system and also successfully located and imaged a number of documented shipwrecks in the lakes. “Ping DSP technology extends sidescan sonar resolution to three dimensions and the data set from the trials is amazing. The 3DSS-DX-450 has a cross track field of view over 200 meters in 10 meter deep water. And the 3D imaging capabilities over the full water column are impressive.”, stated Munday.

Paul Kraeutner of Ping DSP had this to say about the new relationship, “Eric and his team are a first class organization and we are very excited to be working with Subsea 20/20. From our first meeting, it was clear that Subsea 20/20 was a great fit for us and ever since then we have been more and more impressed by their combination of technical knowledge, comprehensive service, and business integrity.”
