| 摘要 |
The invention relates to a system for detecting and locating submerged underwater objects floating between two waters comprising at least one mechanical scanning sonar (2) with a single transmission channel, making it possible to perform the insonification of a first elementary sector (SE1) in a first pointing direction (PA1) using a single first acoustic impulse, said sonar (2) forming a single reception channel able to acquire a first acoustic signal resulting from said insonification, the mechanical scanning sonar (2) being mounted on a carrier (1), designed to advance in a main direction (D), such that the first pointing direction (PA1) is substantially lateral to the carrier (1) and the first elementary sector (SE1) has a wide azimuth opening and a narrower elevation opening, the mechanical sweeping sonar (2) comprising a mechanical pointing device designed to pivot the first pointing direction (PA1) around an axis of rotation substantially parallel to the main direction allowing the sonar to acquire first acoustic signals resulting from insonifications done in different pointing directions. |
