SURFACE TIDAL-CURRENT ESTIMATION DEVICE, RADAR DEVICE, SURFACE TIDAL-CURRENT ESTIMATION METHOD AND SURFACE TIDAL-CURRENT ESTIMATION PROGRAM |
摘要 |
A distribution of surface tidal current velocity vectors is estimated within a short period of time. A surface tidal current estimator 10 is configured including a deriving module 11 configured to derive wave-crest velocity vectors at a plurality of positions within a predetermined range of a water surface, each of the wave-crest velocity vectors being a velocity vector of a wave crest on the water surface, and correcting modules 16 and 23 configured to correct each of the wave-crest velocity vectors derived at the plurality of positions by the deriving module 11, based on one of the wave-crest velocity vector derived inside a predetermined area within the predetermined range by the deriving module 11 and an ocean-wave velocity vector in the predetermined area within the predetermined range, the ocean-wave velocity vector being a velocity vector of an ocean wave. |
