Waves and currents by X-band radar
Waves and Currents by X-band radar
Many offshore operations are critically dependent on the prevailing sea state. To enhance the safety of people, vessels, buildings and environment, routine sea state measurements are required. In coastal areas sea state measurements are needed to support weather and ship routing services. In addition in recent times, wave data gained growing importance in the protection of the coastal zone from eroding forces of wind, waves, and currents. To meet this increasing demand for sea state information, different wave sensors have been developed in the last decades. Special attention has also been given to the use of various remote sensing techniques to measure waves and surface currents. The ground based remote sensing technique described here is based on standard nautical X-band radar generally used for ship traffic control and navigation purposes. Wave measurements by X-Band radar systems are a reliable data source for supporting e.g. offshore as well as harbour operations or ship routing services.
