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.

Land-sea Separation and Sea Surface Zoning Algorithms for Sea Surface Target
Leida xuebao, 2019 Adaptive detection can effectively improve the detection performance of marine surveillance radars; however, the islands or lands introduce discrete or flaky strong clutter, which may result in wrong covariance matrix estimation.

Challenges in radar sea clutter modelling
IET Radar, Sonar & Navigation, 2022 Abstract The ability to detect small targets in sea clutter is still an ongoing challenge, even for modern radar systems. Over the past decade, the development of new radar waveforms and signal processing algorithms has been assisted by an increasingly good understanding of the characteristics of sea clutter.

Entropy Metrics of Radar Signatures of Sea Surface Scattering for Distinguishing Targets
Remote Sensing, 2021 This paper analyzes sea clutter by a random series without assuming the scattering being independent. We quantitated the complexity of sea clutter by applying multiscale sample entropy.

Study on Sea Clutter Suppression Methods based on a Realistic Radar Dataset
Remote Sensing, 2019 To improve the ability of radar to detect targets such as ships with a background of strong sea clutter, different sea-clutter suppression algorithms are developed based on the realistic Intelligent PIxel processing X-band (IPIX) radar datasets, and ...

Overview and Prospects of Research on Sea Clutter Property Cognition
Leida xuebao, 2016 Sea clutter is one of the main limiting factors influencing the target detection performance of nautical radars. The physical mechanism of sea clutter is complex with an abundance of influencing factors, and the non-Gaussian as well as non-stationarity ...

Scattering statistics of rock outcrops: Model-data comparisons and Bayesian inference using mixture distributions [PDF]
, 2019 The probability density function of the acoustic field amplitude scattered by the seafloor was measured in a rocky environment off the coast of Norway using a synthetic aperture sonar system, and is reported here in terms of the probability of false ...
