Abstract Coastal high-frequency (HF) radars are based on the implementation of the “ SeaSonde” technology of the “Coastal Ocean Dynamics Application Radar ” This monitoring system has the objective of environmental monitoring and consists of the installation of two, or more, stations that allow the measurement of surface currents and sea agitation in an area up to 75 km from the coast. Its operation is based on the measurement of the doppler variation and the intensity of the backscattered signal along each azimuth every 5º (000 - 005 - 010 - 015 -… ..), providing a component of the vector. By joining the different components, the final vector is obtained, where the current intensity is represented in two ways (length and color of the arrow) and the direction (direction of the arrow). From this system, it is possible to obtain vector maps of currents and agitation in real-time, carry out pollutant patches tracking and feed assimilation models for forecasting.
