AI Technical Summary
Existing underwater vehicle positioning systems lack sufficient positioning accuracy in complex multipath interference environments, cannot effectively distinguish between direct waves and multipath signals, and lack environmental adaptability, resulting in large positioning errors and poor robustness.
An underwater positioning system combining acoustic propagation modeling and multipath interference suppression includes adaptive underwater acoustic perception, an environmental cognition module, acoustic propagation modeling, multipath suppression and direct wave extraction, as well as multidimensional information fusion and adaptive positioning calculation. Through multimodal perception, dynamic modeling, prior auxiliary signal processing and environmental adaptive fusion, high-precision positioning is achieved.
It significantly improves the accuracy of direct wave identification and positioning in multipath environments, dynamically adjusts the fusion strategy to adapt to complex marine environments, and improves the accuracy of angle matching and the robustness of the system.
