Research on the Combined Detection of Magnetic Anomaly and Shaft‐Rate Magnetic Field Signals

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Magnetic anomaly signal, shaft‐rate magnetic field signal, combined detection. ABSTRACT Due to the stable propagation of magnetic signals in ocean and air, magnetic detection technology has become an effective means for nonacoustic detection. The magnetic anomaly signal and shaft‐rate magnetic signal radiated by underwater vehicles are currently the ...

Pose‐graph underwater simultaneous localization and mapping for autonomous monitoring and 3D reconstruction by means of optical and acoustic sensors

Journal of Field Robotics, Volume 41, Issue 8, Page 2543-2563, December 2024.
Abstract Modern mobile robots require precise and robust localization and navigation systems to achieve mission tasks correctly. In particular, in the underwater environment, where Global Navigation Satellite Systems cannot be exploited, the development of localization and navigation strategies becomes more challenging.

Thruster Modeling and Controller Design for Unmanned Underwater Vehicles (UUVs) [PDF]

, 2009
Thruster modeling and control is the core of underwater vehicle control and simulation, because it is the lowest control loop of the system; hence, the system would benefit from accurate and practical modeling of the thrusters. In unmanned underwater vehicles, thrusters are generally propellers driven by electrical motors.

Head Horn Enhances Hydrodynamic Perception in Eyeless Cavefish

Advanced Science, Volume 11, Issue 44, November 26, 2024.
Blind Chinese cavefish have evolved a unique head horn structure, which is a convergent feature in the eyesight‐reduced cavefish species. In this work, the structure‐function relationships of this specific head horn structure are systemically investigated, adequately revealing that it can enhance hydrodynamic perception and facilitate underwater ...
