A directional wave spectrum obtained from SAR image data is compared with a directly ob
served directional wavespectrumfrom buoydata.TheSAR image was taken during winter storms
in 1994, coincidently with the buoy measurement near Marado island which is the southernmost
island of Korea. In order to get a directional wave spectrum, the linear modulation transfer function
is applied to the image intensityspectrumfrom SAR imagery and maximum entropy method to the
buoy data, respectively. The directional wavespectrum from the SAR imagery shows very similar
patterns in main wave system to the directional spectrum from buoy data.
