Abstract :
From an ERS-1 SAR image over the East China Sea in May 31, 1995, transverse ship waves are detected and analyzed. The original Hough transform is applied to determine the location of the ship its direction of motion and the linear boundary of the V-shaped wake region. Then the one-parameter Hough transform is applied to detect the transverse ship wave pattern in the SAR image. Once detected, the hazy transverse ship wave crests in the SAR image can be best fitted to analytic solutions. From the fitted wave crests, one can estimate the wavelength of the transverse ship wave and hence the speed of the ship
