Sea Clutter Suppression Based on USR-CycleGAN with Real Airborne Radar Data

IEEE International Geoscience and Remote Sensing Symposium
The complex marine environment leads to weak sea surface target echoes, and the clutter suppression effect of traditional radar signal processing methods is limited, which affects target detection.

Sea Clutter Suppression in GEO SAR Imaging of Maneuvering Ships based on L-statistics

IEEE International Geoscience and Remote Sensing Symposium
The integration time of geosynchronous synthetic aperture radar (GEO SAR) is much longer than that of low Earth orbit SAR (LEO SAR), and the non-cooperative motion of ships leads to imaging defocusing.

Sea Clutter Suppression Method Based on a Self-Attention Spatio-Temporal Prediction Network

IEEE Transactions on Aerospace and Electronic Systems
The prediction and suppression of sea clutter have long been challenging issues in the field of maritime target detection. Traditional sea clutter prediction algorithms often struggle to effectively model complex sea clutter data.

Sea clutter suppression and moving target detection method based on clutter map cancellation in frft domain

Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
In order to effectively detect moving target in strong sea clutter, a detection algorithm for moving target based on clutter map cancellation in fractional Fourier transform (FRFT) domain is proposed. Radar data in FRFT domain are noncoherently accumulated with the single pole feedback clutter map (SPFB-CM) in FRFT domain, which are used to suppress ...

Efficient Matrix Sparse Recovery STAP Method Based on Kronecker Transform for BiSAR Sea Clutter Suppression

IEEE Transactions on Geoscience and Remote Sensing
Sea clutter suppression plays a crucial role in maritime moving target indication. However, in the bistatic synthetic aperture radar (BiSAR) system, traditional space-time adaptive processing (STAP) method cannot satisfy the expected performance due to ...

Two-Stage Collaborative Sea Clutter Suppression Based on Subregion Gazing and Reconstruction

IEEE Geoscience and Remote Sensing Letters
Radar target detection is an important technical means for effective monitoring of sea surface targets. Under strong sea clutter, the echo characteristics of some targets with small radar cross sections (RCSs) may be submerged, affecting the performance ...

Suppression of Sea-ice Clutter Observed by a Millimeter Wave Radar

International Journal of Infrared and Millimeter Waves, 2007
Sea-ice clutter was measured using a millimeter wave radar (MWR) with a frequency of 34.86 GHz, the beamwidth of 0.25° and pulsewidth of 30 ns which is located at Mombetsu in Hokkaido, Japan. In this paper, targets are an iron tower and a breakwater which are embedded in sea-ice clutter.

Suppression of Sea Clutter of Skywave Radar Based on AR Model

Applied Mechanics and Materials, 2012
The prediction of chaotic time sequence based on AR model is studied. The forming mechanism of the first-order Bragg lines of sea clutter is analyzed. According to the signal characteristic of sea clutter, a sea clutter time sequence predictor and a skywave radar sea clutter suppression system based on AR model are presented.
