Background

HISAS 1032 is Kongsberg's dual-receiver synthetic-aperture sonar, the sensor payload that pairs with the HUGIN Superior autonomous underwater vehicle. The dual-receiver configuration improves along-track resolution and allows simultaneous bathymetric mapping alongside sidescan imagery, producing sub-decimetre resolution of the seabed at speeds practical for mine-hunting and infrastructure surveys.

It works by combining acoustic returns from repeated pings as the AUV moves, synthesising a longer effective aperture than a physically longer array could achieve at the same depth and speed. Operating at low acoustic frequency also lets it penetrate seabed sediment rather than only image the surface, of particular value in mine countermeasures and seabed-cable monitoring.

Kongsberg markets HISAS 1032 as a standalone payload compatible with third-party AUV platforms, not solely the HUGIN family, giving it a market beyond any single vehicle programme or procurement bid it is named alongside.

Common Questions
What does synthetic-aperture sonar do that regular sonar cannot?
Synthetic-aperture sonar (SAS) combines acoustic returns from multiple pings as the vehicle moves, producing sub-decimetre resolution seabed imagery at operational survey speeds. Regular sidescan sonar at the same speed produces coarser images. HISAS 1032 also maps sediment depth below the seabed surface, which regular sidescan cannot.Source: Kongsberg technical documentation
Why is HISAS 1032 part of the AUKUS Pillar II bid?
In the Kongsberg-DRASS AUKUS bid, HISAS 1032 is the seabed-detection layer: the sensor that finds mines or maps infrastructure. It is paired with HUGIN Superior (the AUV) and hosted aboard the DRASS DG-900 compact submarine. The combination was announced at ILA Berlin on 8 June 2026.Source: Tech Times
Can HISAS sonar be used to protect undersea internet cables?
Yes. HISAS-equipped AUVs can map and monitor seabed cable routes at high resolution. NATO's Task Force X-Arctic, launched 6 June 2026, targets the GIUK gap where 97% of transatlantic internet traffic passes through submarine cables; synthetic-aperture sonar is one of the sensor architectures being evaluated.Source: Naval Technology
