Study On The Chaotic Characteristic Of Sea Clutter Time Series

In this paper, based on the fundamental theory of rough surface scattering and according to the actual sea spectrum models, the one and two-dimensional time-varying sea surfaces are generated by using the method of Monte Carlo simulation. The electromagnetic scattering fields from one/two-dimensional sea surface are evaluated by employing Kirchhoff Approximation (KA). Meanwhile, the mono- and bi-static scattering coefficients and time series of sea clutter are calculated, and the phase space is reconstructed from the sea clutter time series, the correlation dimension and the largest Lyapunov exponent of the reconstructed phase space are also calculated. Furthermore, the dependence of the chaos properties on the incident angle, wind speed and radar frequency is discussed in detail.
