摘要

激光应用系统多以脉冲方式工作。本文以激光在空间信道内的应用为例，探讨了复杂环境下激光应用系统的噪声种类、形成原因。根据小波变换检取信号局部特征的能力，提出了一种基于小波分析的光脉冲检测技术，给出了仿真结果和应用结论。

Abstract

Signals in most laser systems are chiefly given in the form of pulses. This paper discuss?es the sorts and origins of noises in laser systems in complicated environments，taking as an example laser applications in the air channel. Based on its ability in detecting local characteristics of signals by the wavelet transform，the paper sets forth a technique of detecting optical pulses depending upon it. Emulation results and application conclusions are shown.
