Information and Communication Technology Convergence
In this paper, we propose a deep learning-based network that combines multiple pulse repetition frequency (PRF) and velocity resolution uniformization (VRU) techniques to improve target detection in the presence of sea clutter, particularly in scenarios ...

Sea Clutter Suppression Based on Radon Transform at High Grazing Angles
2006 CIE International Conference on Radar, 2006During final guidance, as radar working over sea surface at a very high grazing angle, it is hardly to distinguish target from clutter background due to the strong reflection of the sea surface. A novel method is presented to suppress the sea clutter in this paper. The proposed method based on Radon transform utilizes edge detection technique to find a

An Alternating Proximal Method for Sea Clutter Suppression in Over-the-Horizon Radar Systems
IEEE Geoscience and Remote Sensing LettersThe over-the-horizon (OTH) radar systems are seriously affected by sea clutter. The precise estimation of sea clutter covariance (SCC) plays an important role in suppressing the sea clutter, especially in the case of limited samples.

Matrix Sparse Model Based Spatio-Temporal Spectrum Recovery Method for Bisar Sea Clutter Suppression
IEEE International Geoscience and Remote Sensing SymposiumSea clutter suppression plays a crucial role in maritime moving target indication. However, in the bistatic SAR (BiSAR) system, traditional space-time adaptive processing (STAP) method can’t satisfy the expected performance due to severe range cell ...

A Target Detection Method Based on Feature Transformation for Sea Clutter Suppression
IEEE Signal Processing LettersTo address the poor performance of conventional sea clutter suppression methods when target echoes share the same frequency as sea clutter, this letter proposes a suppression approach based on feature transformation.
