| 摘 要： | 阐述了光电着舰引导激光测距/跟踪单元的工作原理，从人眼安全和大气窗口两方面讨论并确定了激光发射机波段。通过经验公式计算及MODTRAN实验对比研究了1.5x μm全光纤激光的大气透过率。在精确计算大气双程透过率的基础上，分析了激光测距/跟踪单元不同气象条件下的作用距离。在晴与霾两种气象条件下，所设计的激光单元最大作用距离分别为10.8 km和8.5 km，满足光电着舰引导系统对跟踪距离大于6 km的指标要求。

| Abstract: | The working principle of laser ranging/tracking unit in opto-electronic landing guidance was expounded. The laser emitting waveband was discussed and determined from the two main factors, eye-safe and atmosphere-window. The 1.5x μm lasers atmosphere transmittance was studied by comparing the results of empirical formula calculation and MODTRAN experiment. Based on the outcome of the precise calculation of atmosphere transmittance, the operating ranges of the laser unit under different meteorological conditions were analyzed. Results show the maximum operating ranges of the laser unit are 10.8 km and 8.5 km respectively in clear and haze conditions, which meets the requirement of opto-electronic landing guidance system for the tracking distance of more than 6 km. |
