Cooperative Localization for Autonomous Underwater Vehicles [PDF]
International Journal of Robotics Research, 2009 This paper describes an algorithm for distributed acoustic navigation for Autonomous Underwater Vehicles (AUVs). Whereas typical AUV navigation systems utilize pre-calibrated arrays of static transponders, our work seeks to create a fully mobile network of AUVs that perform acoustic ranging and data exchange with one another to achieve cooperative ...

Optimal Kinematic Control of an Autonomous Underwater Vehicle [PDF]
IEEE Transactions on Automatic Control, 2009 This note investigates the motion control of an autonomous underwater vehicle (AUV). The AUV is modeled as a nonholonomic system as any lateral motion of a conventional, slender AUV is quickly damped out. The problem is formulated as an optimal kinematic control problem on the Euclidean Group of Motions SE(3) , where the cost function to be minimized ...

Model-based optimal action selection for Dyna-Q reverberation suppression cognitive sonar
EURASIP Journal on Advances in Signal Processing, 2023 The Doppler shift of low-speed targets is frequently disturbed by the reverberation Doppler spread clutter under the shallow sea. The clutter is generated by underwater scatterers, which increases the difficulty of Doppler estimation.
