Digital representation of split-beam-transducer beam patterns
(ICES CM Documents;1986/B:2, Working paper, 1986)The farfield beam pattern of each of two different split-beam transducers is computed and represented in the axial region by a finite number of constant levels. The accuracy of representation is determined as a function ... -

Experiences using the ES-400, split-beam echo sounder, with special reference to the single-fish recognition criterion
(ICES CM Documents;1986/B:38, Working paper, 1986)Realistic estimates of in situ target strength can be made when the fish concentrations are acoustically resolved into single individuals. In the split-beam echo sounder, as in all other systems available for in situ ... -
A general system for logging information from instruments in the sea.
(ICES CM Documents;1978/B:23, Working paper, 1978)The paper describes a logging system which aims at integrating various forrns for primary data recording into a common standard that can be handled by the same reading and data processing equipment, Some illustrative ... -
In situ target strength observations on haddock
(ICES CM Documents;1986/B:39, Working paper, 1986)In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting ... -
Preliminary results from tests using a high-frequency sonar as trawl-sonde
(ICES CM Documents;1986/B:37, Working paper, 1986)A high-frequency, short-range sonar is tested for trawl-geometry measurements on pelagic and bottom trawls. The sonar was operated on a standard, coaxial trawl sonde cable, and produced excellent images of the trawl ... -

Trial of a New, Split-beam Echo Sounder
(ICES CM Documents;1984/B:21, Working paper, 1984)The first at-sea trial of a new, split-beam echo sounder, the SIMRAD ES380 system, is described following a review of the split-beam principle, outline of its realization in hardware and software, and description of ...
