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 ...

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

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.
