This paper describes the upgrade of an existing wave information retrieval algorithm by employing noise reduction in the pixel do main. Several algorithms for collecting wave information parameters fr om X-band radar image sequences including the wind field and curren t velocity have been developed over the past three decades. Using these algorithms, a band-pass filter (BPF) is applied to remove the n on-wave contribution from the image spectra after the sea surface curre nt velocity has been computed. However, such BPF designs have been both complex and insufficient in removing undesired components in Xb and radar images. For this study, to improve the performance of wav e information retrieval, an efficient noise reductionalgorithm i s incorporated into a regular wave information retrieval process. That is, the proposed algorithm was designed for operation in a more proper manner by effectively removing the undesired components in the pixel domain. Experiment results demonstrate that the proposed algor ithm produces very close estimates to the buoy data records under undesirable noise conditions.
