Arrangements for testing side-scan sonar and multibeam

摘要

The invention relates to the field of sea instrument making and is designed to test the side-scan sonar and multibeam echo sounders in specially engineered landfills. The technical result consists in increasing the accuracy of the coordinates detected by the side-scan sonar and multibeam echo sounders bottom real objects, e.g., bottom mines, fragments wrecked planes, ships, etc. An apparatus for testing side-scan sonar and multibeam sonar comprising simulator underwater object representing mounted on the bottom of the reservoir in a location with known coordinates and depth underwater reflector with prescribed configuration and dimensions, ship-board equipment including a means for determining the current coordinates of the vessel, on which a side-scan sonar checked or multibeam sonar, and its output connected to the computing device for calculating those uschim vessel coordinates and the known coordinates and depth of the simulator installation space underwater object current slant range to the last, which is compared with the value of an appliance slant range and depth of detection simulator.
