Preprocessing LOFARgram through U-Net++ neural network

Preprocessing LOFARgram through U-Net++ neural network

The study of the low-frequency analysis and recording spectrum (LOFARgram) of ship-radiated noise is essential for extracting critical information, such as target motion trajectories. However, the quality of LOFARgrams often degrades due to the inherent stochasticity of ship noise and the interferen...
