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

Radardiff: Improving Sea Clutter Suppression Using Diffusion Models for Radar Images
ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)Marine radar is employed across multiple fields, notably in navigation, meteorology, defense, and security. Marine radar images are highly sensitive to sea clutter, highlighting the crucial importance of sea clutter suppression in radar image processing.

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.

IEEE Transactions on Geoscience and Remote Sensing, 2021
In this article, we propose a multichannel sea clutter model in a spaceborne early warning radar system and analyze the influence of the sea clutter motion characteristics on the space-time adaptive processing (STAP) performance. To establish a multichannel sea clutter model, the 3-D Gerstner wave model is applied to construct the sea surface. Then the

Suppression of the sea clutter in marine radar system
IIEEE International Conference on Acoustics Speech and Signal Processing, 2002The purpose of this paper is to analyze the radar echo signal data in marine radar system, and we tackle a problem on suppression of the sea clutter on marine radar display by using Wavelet Transform, which gives optimum cut-off frequency with time (distance).

Sea Clutter Suppression using EMD-SVD- FRFT Filtering
2019 International Conference on Control, Automation and Information Sciences (ICCAIS), 2019Sea clutter suppression is one of the major measures to improve target detection from sea clutter. Singular value decomposition-fractional Fourier transform (SVD-FRFT) filtering is conducted to suppress sea clutter without impairing the target even when the target and first-order sea clutter are mixed in the Doppler spectrum.

Research of Sea Clutter Suppression Algorithm Based on GPU
Applied Mechanics and Materials, 2012This paper presents an algorithm of sea clutter suppression using graphics processing unit (GPU) to meet the real-time requirement in the general radar terminal system. The main idea is to convert an infinite impulse response (IIR) filter to a finite impulse response (FIR) filter, which is suitable for the parallelization processing of GPU.

A Novel Sea Clutter Suppression Method based on Neural Network
2021 IEEE 4th International Conference on Electronic Information and Communication Technology (ICEICT), 2021In order to suppress sea clutter effectively, it is necessary to estimate the center and width of the power spectrum of sea clutter accurately. Since the complex property of sea clutter, traditional methods cannot estimate the accurate parameters of power spectrum of sea clutter, which leads to the decrease of the clutter suppression performance.

A machine learning approach to radar sea clutter suppression
2017 IEEE Radar Conference (RadarConf), 2017The radar detection of small maritime targets requires special attention to the suppression of sea clutter returns that, in certain circumstances, may be difficult to discriminate from target returns. In this paper, the novel use of machine learning techniques is explored to address this familiar problem.
