Abstract
A drag antenna for a sonar system for detecting and/or locating sources of sound in water includes at least two acoustically sensitive lines positioned side-by-side and laterally spaced apart during a trailing operation. The lines are secured to each other at the leading ends and at the trailing ends by respective connecting element in order to lower the production costs for the drag antenna and to achieve a sufficiently constant lateral spacing between the acoustically sensitive lines.
