Abstract

The invention discloses an image sonar system and an image sonar method for realizing rectangular scanning, which realize the non-blind area scanning of a rectangular scanning area by the match working of multiple groups of single wave beam image sonar heads. The system mainly comprises an overwater comprehensive processor, a plurality of sets of underwater image sonar heads, a data transmission link cable and a sonar head mounting mechanism, wherein the overwater comprehensive processor receives data collected by the sonar heads through a data transmission link, finishes the processing of a single acoustic signal and an acoustic image, carries out comprehensive image synthesis on images of all the single sonar heads according to the corresponding relation of sonar head posture data and addresses and mounting positions of the sonar heads and displays the whole scanned image; the sonar heads adopt a working way of unit and time division, and the addresses adopt dynamic distribution. Theinvention is suitable for and is not restricted to the applications of underwater image scanning, underwater safety protection and underwater monitoring.

Description

technical field [0001] The invention relates to an underwater high-frequency image sonar system and a realization method, which are suitable for underwater image scanning, underwater security protection, and underwater monitoring, and specifically refer to an image sonar system and method for realizing rectangular scanning. Background technique [0002] At present, various image sonar systems are widely used in underwater acoustic image scanning, underwater security, underwater monitoring and many other fields. Traditional image sonar systems use single-beam or multi-beam scanning, and complete acoustic imaging of targets based on target echo signals. The sound pulse is emitted externally, and the receiving matrix receives the target echo signal with a certain beam angle. Therefore, the scanning range of the traditional image sonar system is a fan-shaped area, the scanning blind area is large and the "acoustic shadow area" is easy to exist, it is easy to lose the target, an...
