Phase space analysis of noise for oceanic lidar

摘要: 通过对混沌信号以及海洋激光雷达接收信号噪声的相空间分析,探讨了由时间序列重构相空间时参数选择的影响。重建了确定信号、随机信号、混沌信号和海洋激光雷达接收信号噪声的相空间。经过以上工作,初步掌握了重构相空间时参数选择的规律,明确了确定信号、随机信号和混沌信号各自的相空间特性,并发现海洋激光雷达接收信号噪声与混沌信号有相似的相轨迹。

Abstract: First we discuss the effect of the parameter selection on the reconstruction of phase space through the analysis of chaotic signal and the signal received by laser underwater target detection system.Then we analysis the phase space of cosine,random,chaos and experiment signal,and find that the phase space of the experiment signal is similar with chaos phase space,but different from the random phase space.
