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.

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-

Chaotic modelling of sea clutter
Electronics 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.

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
