This program includes development of both sonar systems and software for SAS signal processing. A result of this development is the HISAS 1030 wideband multi-aspect interferometric SAS (see picture below). This system is delivered to the Royal Norwegian Navy as part of the HUGIN 1000-MR.
Synthetic aperture sonar processing is very closely related to synthetic aperture radar (SAR), seismic imaging and ultrasound beamforming. One of the fundamental challenges in SAS beamforming is processing speed. Large amounts of data need to be needs to be formed into images fast.SAS signal processing overview
