基于混沌学的海杂波分析

A Study of Sea Clutter Based on Chaos

介绍关联维和 L yapunov指数等用于表征未知混沌动态系的重要概念及算法 ,描述海杂波的动态特性 ,进行海杂波的计算机模拟。通过对模拟海杂波的混沌分析得出 ,海杂波有有限的关联维和正的 L yapunov特征指数 ,说明海杂波是混沌的。

This paper introduces the correlation dimension and the Lyapunov exponent that are the important properties of the chaotic dynamics system, and describes the dynamics characteristics of sea clutter. Simulations of sea clutter are made on computer. Analysis of simulated sea clutter indicates that sea clutter is a chaotic, dissipative and physically realizable system.
