Hydroid Delivers First High Resolution Interferometric Synthetic Aperture Sonar
POCASSET, Mass., Mar. 14, 2018 /PRNewswire-AsiaNet/--

-- Naval Oceanographic Office accepts REMUS 600 with first modular bathymetry 
payload with HISAS 2040, EM 2040 sonars and an integrated navigation solution

Hydroid, Inc., a subsidiary of Kongsberg Maritime and the leading manufacturer 
of marine robotics, announced today that it successfully delivered the first 
modular bathymetry payload with the new HISAS 2040, a high resolution 
interferometric synthetic aperture sonar (HISAS). The system, engineered and 
manufactured at Kongsberg Maritime in Horten, Norway, was delivered to the 
Naval Oceanographic Office (NAVOCEANO).

Designed with the latest technology and capabilities, the 2040 bathymetry 
payload was installed on a Hydroid REMUS 600 autonomous underwater vehicle 
(AUV). The system was delivered fully integrated with navigation, and is 
calibrated to provide full swath, gap-filled imagery and bathymetry in a small 
form factor, modular AUV package. The HISAS 2040 sonar provides resolution 10 
times higher than conventional sonars and offers high-performance real-time 
processing and sonar quality assessment. NAVOCEANO Project Manager, Doug Cronin 
said the HISAS 2040 sonar performance is, "Impressive. Some of the best imagery 
I've ever seen."

The HISAS 2040 is able to build up a series of synthetic aperture sonar (SAS) 
images that represent different observation angles. Through this multi-aspect 
imaging, an AUV operator is able to obtain an extra dimension in the data set 
since many complex objects have a high aspect-dependent echo and shadow 

"The HISAS 2040 sonar brings an entirely new dimension to the synthetic 
aperture sonar market," said Duane Fotheringham, president of Hydroid. 
"Compared to traditional sonars, the HISAS 2040 sonar reduces survey time and 
provides superior data quality, which is particularly useful in oceanographic 
surveying and mine countermeasure operations. We are excited to be offering 
this new Kongsberg technology on our REMUS vehicles."

The HISAS 2040 frequency range is 220-280 kHz, with a typical 
operational-performance range of 130m on each side of the vehicle at 2 m/s. It 
has a practical resolution of 5cm x 5cm at all ranges.
