| 摘 要： | 利用实测的引信海洋回波数据，将引信海洋回波假定为双通道调制模型，分析了其混沌 特性.。数据计算表明两个通道的调制信号均存在分数维和正的Lyapunov指数。在假定模型下对 调制信号的混i电特性分析比直接对海洋回波信号分析更加稳定，通过MontCarlo法仿真计算，对比 分析了两者所计算的混沌参数分布情况，证明了该假定模型的合理性。

| Abstract: | On the assumption that the oceanic echo signals of fuse are double-channel modulated model, the chaotic characteristics were analysed using the detected data of fuse. The result of calculation shows that both the modulated channels possess the fractional dimension and at least one positive Lyapunov exponent. It is concluded that, compared with the simple echo signal analysis, the analysis of chaotic parameters using presented model is more efficient and accurate. Also, the rationality of the assumption is proved. |
