An algorithm for estimation of wave parameters from X-band marine radar images
An algorithm based on Radon transform (RT) is proposed to estimate wave parameters from X-band marine radar images. First, an initial guess of wave direction is determined from the first image of an image sequence. Then, sub-images located in the initial guess of wave direction from an image sequence are used to determine wave parameters, including wave direction, peak wave period, and mean wave period. The algorithm is tested using radar and buoy data collected in a sea trial in the vicinity of the east coast of Canada. Compared to the traditional Fourier-based technique, the wave parameter estimation results are shown to be improved by the proposed algorithm.
