Doppler characteristics of sea clutter. [PDF]
, 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.

Infrared Small Marine Target Detection Based on Spatiotemporal Dynamics Analysis
Remote Sensing, 2023 It is a big challenge to detect and track small infrared marine targets in non-stationary and time-varying sea clutter because the signal is too strong to be estimated.

Low Observable Radar Target Detection Method within Sea Clutter Based on Correlation Estimation
Remote Sensing, 2022 The long-time coherent integration can effectively improve the detection ability of radar targets. However, this strategy usually shows poor effect in resisting the sea clutter, which produces difficulties for accurate estimation of sea clutter ...

The Dynamic Sea Clutter Simulation of Shore-Based Radar Based on Stokes Waves
Remote Sensing, 2022 The sea clutter model based on the physical sea surface can simulate radar echo at different times and positions and is more suitable for describing dynamic sea clutter than the traditional models based on statistical significance. However, when applying

Bistatic Sea Clutter Suppression Method Based on Compressed Sensing Optimization
Applied Sciences, 2023 In order to reduce the sea clutter interference in the detection of sea surface targets, we propose a bistatic sea clutter suppression method based on compressed sensing optimization in this paper. The proposed method mitigates the interference effect by

Remote 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
Remote 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-
