dc.description.abstract | Most applications of echo integration involve use of a fixed
single-beam transducer that is rather narrow and downwards-oriented. It
is often desired to sense fish in other directions, for example, to assess
components of the fish stock which may be avoiding the surveying vessel.
To assist in discussions of a general solution, a cylindrical sonar design
is proposed. Such a sonar would be carried in a towed body, allowing
detection and localization throughout the plane transverse to the vessel
track. Beam patterns, equivalent beam angles and other measures of
performance are computed for a range of frequencies and aperture sizes. | no_NO |
