Title: Method and apparatus for detecting vessel by cross-fan beam
Inventor: MOGI TOSHINOBU
IPC: G01S15/89
Filed: 2002-06-05
Abstract: <P>PROBLEM TO BE SOLVED: To detect the draft and size of a vessel and the loadage of cargoes.  <P>SOLUTION: Beams are irradiated from a sea bottom toward a sea surface with a sonar using cross-fan beams. Sound waves (echoes) of each beam reflected from the vessel are divided by a unit of time, and the state of reception of each beam in a unit of depth is collected. Then characteristics are extracted to detect the draft, size, etc. of the vessel. By dividing data by the unit of depth and processing the section immediately before the reception of the reverberation of the sea surface and preceding sections, the reverberation of the sea surface is excluded. In addition, by detecting even the intensity of the echoes, the echoes of the vessel intenser than the reverberation of the sea surface are extracted and separated from the reverberation of the sea surface. The state of reception of the echoes is collected in the unit of depth, and the size of the vessel is computed from the area and width of the echoes. The draft is computed from the depth at which the echoes occur to determine the loadage.  <P>COPYRIGHT: (C)2004,JPO
