摘　　要：文章首先对航天发射场的清洁大气、霾、雾、云等气象因素的激光反射特性进行了分析;在此基础上,运用激光雷达方程,采取高度规格化的信号处理方法,对不同高度、不同浓度和厚度的云层的激光反射特性进行了分析和仿真;最后,归纳出了重点对云层高度、厚度和种类进行判断识别的几点结论;文章的研究成果对利用激光雷达进行气象观测,确保航天发射场的航天器、制导武器安全升空,具有较高的参考价值。The laser scattering character of weather factor such as haze, fog and cloud is analyzed at first. Based on this part the laser scattering character of cloud layer with different density and thickness at different height was modeled, analyzed and simulated adopting method of height normali- zation with equation of Iidar. The analysis of scattering signal can be used to judge the height and thickness of cloud has been concluded. Analysis result of the laser scattering character of cloud layer is the theoretical basis of meteorology observation with lidar and it can be used for blastoff of spacecraft.
