Abstract
In this paper, to estimate the distribution of the wave height by the along-track interferometry SAR (AT-InSAR) precisely, the relationship between the wave height and the sea surface velocity measured by the AT-InSAR was clarified and a method to estimate the wave height from the measured sea surface velocity was developed. In addition, to check the capability of the ocean waves observation by the AT-InSAR, the preliminary observation for the ocean waves was performed. The observation area is the sea surface at 10 km off the coast of Kushiro, south-east to Hokkaido, JAPAN on the 4th of March 2015. The wind speed was 8～10m/s during the observation, and the significant wave height and period were 1.4m and 6.0s. The observation was performed in 2 directions and the accuracy of the estimation results was checked. The significant wave height measured by the AT-InSAR agreed with it measured by the wave gage located close to this observation area.
