Shipborne HFSWR Target Detection in Clutter Regions Based on Multi-Frame TFI Correlation
Remote Sensing, 2022 High-frequency surface wave radar (HFSWR) is an important marine monitoring technology, and this new regime of radar plays an important role in large-scale, continuous early-warning monitoring at sea. In particular, shipborne HFSWR has wider applications

Modelling of sea clutter with gaussian mixtures and estimation of the clutter parameter
Proceedings of the IEEE 12th Signal Processing and Communications Applications Conference, 2004., 2004 In order to model sea clutter, we propose to use a generalized distribution which is valid for different background statistics, like low and high sea states. The envelope detector's input statistics are assumed to be a Gaussian-mixture (GM). A new background probability density function (pdf) resembles Rician mixtures.

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.

Research on the Influence of Ocean Environment on Sea Clutter [PDF]
, 2011 Generally sea clutter is regarded as the radar clutter echoes, which interferes in target acquisition ability of marine radar. Synchronously the ocean environment parameters affect the intensity and other aspects of sea clutter.

Nonlinear Dynamics of Sea Clutter [PDF]
International Journal of Navigation and Observation, 2008 We review experimental evidence for the nonlinearity of sea clutter and the role of the z‐parameter or Mann‐Whitney rank‐sum statistic in quantifying this nonlinear behavior in the context of a hybrid AM/FM model for sea clutter, viewed as a cyclostationary process. An independent theoretical derivation of the stochastic dynamics of radar scattering in

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 ...

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.

Blind sea clutter suppression for spaceborne gnss-r target detection [PDF]
, 2019 It has been demonstrated that delay-Doppler (DD) maps (DDMs) retrieved from spaceborne Global Navigation Satellite Systems Reflectometry missions contain sea clutter and also potential sea targets.
