Underwater robotics, acoustic signal processing
Work description
Study existing passive acoustic detection methodologies and tracking algorithms in underwater environments. Analyze the physics of underwater acoustic propagation, including effects such as refraction, absorption, and background noise. Identify acoustic sensor network architectures (hydrophones, linear arrays, distributed arrays, etc.) and their data models. Implement passive and active detection algorithms based on cross-correlation, beamforming, or other methods. Estimate Time Difference of Arrival (TDOA), Direction of Arrival (DOA), and fusion of data from multiple receivers. Develop multi-target tracking techniques (e.g., extended Kalman filters, particle filters, or Multiple Hypothesis Tracking). Simulate moving mobile acoustic sources. Evaluate the robustness of algorithms to noise, multipath, etc. Define and evaluate performance metrics: location accuracy, detection rate, computational consumption, etc. Integrate the algorithms into a real-time system (on-board hardware or ground station). Conduct test campaigns in a controlled environment (tank) and in the open sea. Calibrate and validate the system with known (ground truth) and unknown sources.
