摘　　要：以机载海洋激光雷达试验数据为依据，证明了海洋激光雷达系统的相关维是一个分数，而且至少有一个正的李雅鲁诺夫指数，进一步揭示了其噪声内在的混沌特性．此项研究有可能为提高海洋激光雷达系统的检测性能提供了一条新的途径．Based on the oceanic lidar test data, it is proved that the correlation dimension of the oceanic lidar system is a fraction and there is at least one positive Lyapunov exponent. The inherent chaotic features of the signal noise of the oceanic lidar system are therefore further clarified. This investigation has provided a new path for improving the detecting performance of the oceanic lidar system.
