Abstract:Waves are the most obvious surface stripy features in the highresolution synthetic aperture radar (SAR) images of the ocean. In order to effectively detect or retrieve the nonwave phenomena from SAR ocean images, the interference from the waves need to be suppressed. The traditional ocean wave clutter suppression method is mainly based on the geometric texture of the images, by means of filtering in the special frequency domain or wavelet domain. However, the regions in the frequency domain or wavelect domain which contain information of the waves may also contain spectra of other nonwave objects, thus leading to an unwanted information losing when filtering on these regions. In this paper, we propose a new ocean wave clutter suppression method based on series of SAR images. We use the differences of the two images in combination with the wave dispersion relation to cancel the wavestripe in the images. The main point of our method is to use both the geometric information and the temporal information, thus enable us to suppress the waves selectively while leaving the nonwave information unharmed. In addition, we use real SAR data to validate it. The result of the experiments shows that the proposed method can effectively suppressed the wave stripes and maintain the nonwave information in the images. Our method outperformed the traditional filterbased method as well.
