Algorithm for Detection of Current and Water-depth using X-band Marine Radar

AbstractThe object of this study is to present an algorithm to estimate ambient current and water depth from sea clutter images obtained from X-band marine radar. In the present article, numerically synthetized images are utilized to verify the accuracy of the proposed algorithm. Synthetized sea surface images were analyzed for regular directional waves as well as directional random waves with current and without current. Estimation of currents from sea surface images for cases of known water depth showed good agreement with exact current velocity. However, we have some computational difficulty when prior water depth is unknown
