Target Detection in Clutter/Interference Regions Based on Deep Feature Fusion for HFSWR
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 High-frequency surface wave radar (HFSWR) is of great significance for maritime detection, but in the HFSWR echo signal, ship targets are often submerged in a variety of clutter and interference, making it difficult to detect vessels.
