Automatic LOFAR Line-Spectrum Extraction with Hybrid Dataset Construction and a Continuity-Aware U-Net

Line-spectrum features in ship-radiated noise are essential for the analysis and recognition of passive sonar targets. Robust automatic extraction from low-frequency analysis and recording (LOFAR) spectrograms remains challenging in underwater acoustic environments owing to strong background fluctuations and interferen...

Causal neural set filtering for online multi-target tracking

Causal Neural Set Filtering (CNSF) is proposed, a neural set filter that encodes only current measurements while carrying past evidence in a structured recursive track state that imposes soft one-to-one constraints, propagate association-induced state uncertainty, and support existence estimation under missed detection...
