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
