高频波段海洋回波信号表现了非线性和频谱时变性 .传统的谱分析方法 ,无法反映回波信号在时间上的演化规律 .本文应用混沌动力学方法分析和计算了高频波段海波回波信号的混沌特性参数 ,并通过高频地波雷达实测数据的验证 ,首次得到了高频无线电波海洋回波信号呈现混沌特性的结论 .这一结论对高频雷达目标探测和海态遥感研究都具有重要意义 .
The high-frequency band marine echo signal shows the nonlinearity and the time-varying spectrum, and the traditional spectral analysis method can not reflect the evolution rule of the echo signal in time.In this paper, the chaotic dynamics method is used to analyze and calculate the high frequency band sea wave back The chaos characteristic parameter of the wave signal and the conclusion that the chaotic characteristic of the high frequency radio wave ocean echo signal is obtained for the first time through the verification of the measured data of the high frequency ground wave radar.The conclusion is that the high frequency radar target detection and the ocean remote sensing research All have important meaning.
