Available in PDF, EPUB and Kindle. Book excerpt: The Joint Ocean Wave Investigation Project (JOWIP) was conducted to evaluate the detectability of ocean wave structures on imaging synthetic aperture radar (SAR). This project used Kelvin surface ship wake patterns generated under controlled and well documented surface environmental conditions to isolate SAR image parameters. Use of waves of known wavelength and direction provide the opportunity to evaluate the SAR contribution to ocean wave forecasting. SEASAT-like images made with L-band SAR are presented: (1) to suggest how ship-generated surface roughness combines with the velocity-bunching mechanism in calm ocean areas to produce the unusually narrow wakes observed for azimuth-traveling ships on SEASAT images; and (2) to estimate conditions under which SAR image modulation mechanisms can be expected to produce wake images. A method is described for using the Kelvin transverse ship wake wave component to quantitatively evaluate the contributions of various SAR ocean wave imaging mechanisms. It makes use of the narrow sector of surface roughness generated by a ship along its track to produce SAR images of the longest waves in its wake system on flat calm water.

Download or read book Ocean and Ship Wave Modification by a Surface Wake Flow Pattern written by O. M. Griffin and published by . This book was released on 1988 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean surface waves are altered by interactions with mean and fluctuating surface currents. These waves may be ambient or ship-generated, or may be a combined system produced by both sources of generation. An important wave-current interaction is caused by the interaction of the waves with the surface wake produced by the passage of a surface ship. Remote observations of a ship wake using synthetic aperture radar (SAR) show distinct features such as a dark trailing centerline region and bright-line images aligned at some angle to the ship's path. The dark region of relatively low radar backscatter is usually associated with a 'dead winter' region which is relatively devoid of short wave components, while the bright line feature suggests a region of enhanced radar return within the apparent angular confines of the ship's Kelvin wave pattern. In this report the interactions of ship generated Kelvin waves and ambient waves with the momentum wake of a surface vessel are studied to assess the effectiveness of the momentum wake in the generation of these remotely-observed features. Other factors such as the limiting wave steepness at the onset of wave breaking also are considered. Keywords: Ocean waves, Wake detection, Marine hydrodynamics, Wake, Ship waves. (JHD).
