Phase space reconstruction for noise of the oceanic lidar |
| |
| Abstract: | In this paper,we first discuss the effect of parameters choosing on phase space reconstruction through the chaotic signal and the signal received from the oceanic lidar.Then we reconstruct the space of the three types signals of determinate signal(cosine),random signal,chaos and experimental signal.We preliminarily know the regular pattern to choose the parameters and the phase space character of the three types of the signals,and find that the phase space of the experimental signal is similar to chaos',but different from random's |
