About SeaDarQ

The SeaDarQ system uses radar processing technology to extract hydrographic, oceanographic and environmental information from radar waves.

Over the past 25 years the Dutch Governmental Institute TNO has researched and completed extensive experiments focused on radar and antenna design. These experiments have successfully demonstrated how radar waves reflected from the sea surface contain valuable information which can be extracted using complex algorithms to process radar clutter. This information is very valuable in the fields of oceanography, hydrography, maritime safety and environmental protection. In 2003, the Dutch Institute TNO formed a joint venture with Tech 5 B.V., a company designing and building electronic measuring systems. Through this venture the company SeaDarQ B.V. was formed. The advanced technology developed by TNO and the expertise of Tech 5 B.V. was exported and incorporated into industry through SeaDarQ B.V.

Since its formation in 2003, SeaDarQ has been delivering products worldwide using a distribution network and OEM partners with local service facilities. Its customers include Coast Guards, Ship-owners, VTS-integrators and Port Authorities.

In 2011 SeaDarQ has been acquired by Nortek B.V., Dutch subsidiary of Nortek AS based in Norway. Nortek group has an extensive network of offices and distributors around the world. Main offices are located in US, China, Brazil, Norway and the Netherlands.  Nortek has enjoyed an annual revenue growth of 20-25% per year. The annual revenue of Nortek AS for the first time hit US$ 10 mill in 2006.  Nortek B.V. will continue to supply Seadarq products and aims to provide combined technology solutions to the benefit of its worldwide customer base.


Nortek provides a wide range of instruments to measure currents and waves in the ocean, sea, river and laboratory. See the movie below for a short introduction or surf to www.nortekgroup.com.
