摘要：This paper deals with the use of the wave-radar for sea-state monitoring. The radar used here is popular as marine radar. SEA STATE monitoring by X-band Mare Radar system is becoming increasingly interesting, also due to its spatial resolution, which is much higher than the resolution of the relatively more common high-frequency (HF) coastal radars. In addition, compared to HF radar, X-band radar systems offer an improved operational flexibility; due to their small dimension, low weight, and easy installation, it is possible to install them even on a movable platform and from there to scan the sea surface with high temporal and spatial resolutions. The technique of high resolution two dimensional radar imaging is called as synthetic aperture Radar(SAR). SAR is implemented here to retrieve the high resolution wind and wave fields from image sequence. From the technological standpoint, the main interest lies in the adoption of a system installed on a movable platform; this feature is imp ortant since it offers a good flexibility in the choice of the spatial and temporal observation modalities. Operational analysis errors tend to be reduced slightly by our use of SAR observations in surface wind retrieval.
