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

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.

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.

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.
