It is necessary to examine EERS1-SAR imaging mechanism of the sea surface for the ocean wave observation by using EERS1-SAR images. In this study, we performed a numerical simulation to examine EERS1-SAR imaging mechanism of ocean waves. In the numerical simulation, a two-dimensional wavenumber spectrum was calculated from the benchmark directional wave spectrum by a quasi linear theory. In addition, inversely to estimate the directional wave spectrum from waves visualized by the EERS1-SAR, we made a sequential analysis using the quasi-linear theory to calculate a two-dimensional wavenumber spectrum of a SAR image from the directional wave spectrum observed by wave gage array, and verified the validity of the analysis and clarified the problems of the inverse analysis that estimated the directional wave spectrum from EERS1-SAR images. It is clarified from the sequential analysis using the quasi-linear theory that the directional wave spectrum can be estimated from the SAR image.
