1
Valid for a still water surface.
2
For a water surface with waves.
3
The accuracy of the wave parameters is not limited by the radar sensor, yet it is defined by the stochastic
nature of sea-surface measurements.
4
SWAP is the Standard Wave Analysis Program, in accordance with the applied standards of the Dutch
Ministry of Infrastructure and Environment and of the International Association of Oil and Gas producers.
Used on 20 [min] data block.
5
The wave period is not compensated for the horizontal motion. Hence, for a moving vessel, the sensor
measures the wave period as encountered by the vessel.
