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 ...

Overview and Prospects of Radar Sea Clutter Measurement Experiments
Leida xuebao, 2019 In complex marine environments, sea clutter greatly affects the detection performance of maritime targets. Because the influencing factors of sea clutter are numerous and the mechanism is complex, there are great difficulties in feature description and ...

Statistical analysis of bistatic and monostatic sea clutter
IEEE Transactions on Aerospace and Electronic Systems, 2015 In this work, we analyze the sea clutter data collected simultaneously by the bistatic and monostatic nodes of an S-band netted radar system under different out-of-plane geometries. The empirical distribution of sea clutter data are fitted to some known heavy-tailed distributions, and the sea spikes statistics are examined.

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
