Marine traffic data, for example, course, speed, gross tonnage and shape of vessel are collected in a marine traffic survey. These data were estimated by using a high resolution radar and effective image processing of an anchoring vessel. Authors made a study on the reflected power of radar wave which was caused by the edges of a target considering the fresnel zone. We indicated that the patterns of the fluctuant radar wave reflected by the edge of a vessel resembled closely the antenna reception patterns. We detected the bow and stern of the vessel within the domain of radar echo and made attempt to estimate the length of the vessel by taking account of the first fresnel radius and the beamwidth corresponding half-power points.
