Number: 367/88
Name: Communications, electrical: acoustic wave systems and devices > Echo systems > Side scanning or contour mapping sonar systems
Description: Subject matter in which the paths of acoustic waves to and/or from the transmitter-receiver are directed laterally and downwardly into a body of water from a moving vessel on the body of water or in which a topos:graphical record of the bottom of the body of water is produced from acoustic waves received at the moving vessel.
