It contains plenty of ocean wave and sea surface current information in the sea clutter images formed by X-band marine radar’s echo. Applying the method to calculate the significant wave height from the SAR imagery, which supposes the significant wave height in linear relation with the square of the signal-to-noise ratio of radar images, the significant wave height has been obtained from estimating the images of X-band radar. The experimental data were analyzed in the Small Mai-island sea area. Firstly comparing the effect of filtering direct current versus estimating result, deriving the significant wave height estimated by counting the signal-to-noise ratio after filtering direct current which is match better; then according to wave height measured by wave buoy, analyzing low and high wave height to do linear fit and gain calibration coefficient separately, the significant wave height evaluated is all the more precise.
