The sector-scanning sonar for ensuring of the surface displacement high-speed ships’ movement security

摘要

In the article are considered certain new hydroacoustic facilities for the underwater conditions illumination in udorder to protection of the surface displacement high-speed ships’ movement. The scanty depth under the ship’s keel and udcollision with free-drifting and fixed underwater objects apply to number of basic navigation dangers. It is considered udthe sector-scanning sonar of underwater space in front of ship, in which composition a depth sounding channel is taking udpart. The developed specially designed signal processors, which are realized on the basic of modern soft-hardware udfeatures, the usage of complex sounding signals, enabled us to increase sonar surveying efficiency in conditions of the udhigh-speed displacement ships considerably.
