Sea Clutter Suppression Based on Selective Reconstruction of Features
2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019This paper presents a sea clutter suppression (SCS) method for single-channel maritime radar based on a deep Convolutional Neural Network (SCS-CNN), which consists of an encoder and a decoder. First, the encoder is used to extract depth features of the original Range-Doppler spectrum obtained from sub-aperture echoes.

Research on Sea Clutter Suppression Using Sparse Dictionary Learning
2019 IEEE 8th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2019Due to the interference of the strong sea clutter, it’s difficult to detect marine weak targets and clutter attenuation is the key to improve detection performance. A sea clutter suppression method based on sparse dictionary learning was proposed to attenuate sea clutter and thus enhance the detection performance.

A Sea Clutter Suppression Method With Graph Neural Network for Maritime Target Detection
IEEE Sensors JournalRadar is widely applied in maritime target detection. However, the performance of sea-surface target detection in complex ocean environments is limited because of the low signal-to-clutter ratio (SCR).

Sea Clutter Suppression for Radar PPI Images Based on SCS-GAN
IEEE Geoscience and Remote Sensing Letters, 2021The problem of strong sea clutter, e.g., sea spikes, may bring in low signal-to-clutter ratio (SCR) and cause great interference to radar marine target detection. However, the sea clutter suppression ability of current algorithms is limited with poor generalization under complex marine environment.

Ionospheric Decontamination and Sea Clutter Suppression for HF Skywave Radars
IEEE Journal of Oceanic Engineering, 2005In this paper, a cascaded correction and suppression method of reducing ionospheric phase path contamination and sea clutter to enable detection of targets travelling at speeds near the Bragg Doppler is addressed. The Hankel rank reduction (HRR) technique based on singular value decomposition (SVD) has been used to estimate the ionospheric phase ...

Enhancing Sea Clutter Suppression with Attention Weight Transfer LSTM Architecture
International Conference on Signal Processing SystemsSea clutter suppression remains a critical challenge in maritime radar systems. While the short-term predictability of sea clutter enables suppression via time-series prediction, traditional linear model fails to address its nonlinear dynamics, and ...
