Hayden is senior principal engineer in the Mapping division of Kongsberg Discovery. Hayden received a B.E. (Hons I) and PhD in Electrical and Electronic Engineering from the University of Canterbury in 1999 and 2003 respectively. After completing his PhD work in SAS imaging and autofocus, he worked a period as a post-doctoral consultant and among other projects worked on imaging and autofocus algorithms for the Northrup Grumman slow-speed SAS system. In early 2004, he joined the Norwegian Defence Research Establishment (FFI) working for 7 years as a Scientist / Senior Scientist within the HUGIN autonomous underwater vehicle research team on SAS imaging sensors. During that period Hayden primarily performed research into SAS system design, beamforming, motion-compensation, micro-navigation and interferometry--among other things contributing heavily to hardware design for the HISAS 1030 system and the HISAS 1030 SAS processing software. In 2011 he joined Kongsberg Maritime as a Senior Principal SAS R&D Engineer and works on SAS system design and implementation. Since 1999 he has authored and co-authored over 70 widely cited international papers on SAS.
KONGSBERG Synthetic Aperture Sonar – High-Resolution Seafloor Imaging with HISAS2020
⏰ 13:00-14:00
📌 South Gallery Room 13
This workshop provides a technical introduction to Synthetic Aperture Sonar (SAS) and presents the new HISAS2020 system. The session covers how SAS achieves high resolution independent of range, how HISAS2020 is engineered for integration on multiple platforms, and how real-time processing tools can be used to optimize data quality. Participants will see how key parameters such as platform alignment, navigation accuracy, and sound velocity structure influence SAS performance, and how these effects can be visualized and corrected during processing.
Participants will learn:
- Fundamentals of Synthetic Aperture Sonar and how SAS differs from conventional side‑scan and multibeam systems.
- Architecture and key components of the HISAS2020 system.
- Data‑flow overview from raw acoustic returns to motion compensation, beamforming and image formation.
- How real-time quality assessment tools visualize geometry, alignment, navigation consistency, and sound velocity effects during processing.
- Typical operational scenarios and expected performance envelopes for HISAS2020.
