By analyzing the phase space of the chaotic signal and the received signal noise of the ocean lidar, the influence of parameter selection when reconstructing the phase space by time series is discussed. Reconstructed the phase space for determining the signal, stochastic signal, chaotic signal and ocean lidar receiving signal noise. After the above work, the rule of parameter selection in reconstructing phase space is preliminarily mastered, and the phase and space characteristics of each signal, stochastic signal and chaotic signal are determined clearly. It is found that there is a similar phase trajectory between the received signal noise of ocean laser radar and the chaotic signal.
