Infrared sea clutter suppression method based on gradient filtering
AOPC 2022: Optical Sensing, Imaging, and Display Technology, 2023Point-clutter and strip wave often exist in infrared images of sea surface, which will cause great disturbance to ship target detection. In most cases, the noise in infrared image can be suppressed by image denoising.

Sea Clutter Suppression Driven by Convolutional Neural Network in ArcSAR
2025 22nd European Radar Conference (EuRAD)Conventional sea clutter suppression algorithms are highly dependent on accurately modeling wave characteristics. Several stochastic models have been proposed; however, the large number of variables, such as sea state, grazing angle, radar geometry, and ...

Shipborne HFSWR Sea Clutter Suppression Method Based on MultiDomain Information Synergy
IEEE Geoscience and Remote Sensing LettersDue to the integrated effect of many factors including nonuniform wave motion and shipboard platform motion, the echo signals received by shipborne high-frequency surface wave radar (HFSWR) often suffer from issues such as sea clutter spreading.

Nonhomogeneous Sea Clutter Suppression Using Complex-Valued U-Net Model
IEEE Geoscience and Remote Sensing Letters, 2022This letter considers the problem of target detection in the nonhomogeneous sea clutter environment and proposes the complex-valued U-Net (CV-UNet)-based clutter suppression method. Specifically, first, the complex signal features of radar echo sequences

Sea Clutter Suppression For Marine Surveillance Radar Based On Generative Adversarial Learning
IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023Marine surveillance radar plays an important role in marine environment monitoring, however, its detection performance is often affected by sea clutter. In this paper, we consider the sea clutter suppression process as the mapping from clutter radar data

Online Dictionary Learning Techniques for Sea Clutter Suppression
2020 IEEE Radar Conference (RadarConf20), 2020Maritime airborne surveillance radars operating at high grazing angles experience significant sea clutter returns with a time and range-varying Doppler spectra, thus making the detection of small targets extremely difficult. Many target detection schemes assume models for the amplitude distribution that require estimation of specific parameters.
