A Sea Clutter Suppression Method Based on Machine Learning Approach for Marine Surveillance Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Marine surveillance radar is widely used in marine monitoring for its ability of observing sea surface all-time and all-weather. However, the radar target detection performance is seriously affected by the existence of sea clutter.

Doppler characteristics of sea clutter. [PDF]

open access: yes, 2010
Doppler radars can distinguish targets from clutter if the target's velocity along the radar line of sight is beyond that of the clutter. Some targets of interest may have a Doppler shift similar to that of clutter. The nature of sea clutter is different in the clutter and exo-clutter regions.

Sea Clutter Suppression Using Smoothed Pseudo-Wigner–Ville Distribution–Singular Value Decomposition during Sea Spikes [PDF]

open access: yesRemote Sensing, 2023
The detection of small targets within the background of sea clutter is a significant challenge faced in radar signal processing. Small target echoes are weak in energy, and can be submerged by sea clutter and sea spikes, which are caused by overturning ...

Sea Clutter Amplitude Prediction via an Attention-Enhanced Seq2Seq Network [PDF]

open access: yesRemote Sensing, 2023
Sea clutter is a kind of ubiquitous interference in sea-detecting radars, which will definitely influence target detection. An accurate sea clutter prediction method is supposed to be beneficial while existing prediction methods are based on the one-step-

Chaotic modelling of sea clutter [PDF]

open access: yesElectronics Letters, 1992
In the letter we present calculations based on experimental radar data which confirm the chaotic nature of sea clutter. In particular, the results of the calculations show that the first Lyapunov exponent of sea clutter is indeed positive and around 0.015. Such a result is an inherent characteristic of a chaotic process.
