Joint Motion Error Estimation Algorithm for Multibeam Synthetic Aperture Sonar
Multibeam echo sounder (MBES) and synthetic aperture sonar (SAS) are effective image sonar systems used as the major underwater observation instruments. The MBES system can get the fullscan detection without gaps, while the resolution on the along-track ...

Topology‐based Visual Analysis of Hydrothermal Plumes
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

A Design Method of Image Sonar
Abstract By analyzing the underwater high-speed target tracking and positioning, image sonar was determined as the solution. An image sonar system is constructed. According to the functions of each part of the image sonar, the transducer array, receiver, transmitter and image generation signal processing software are designed.

Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...
