摘要
阐述了大气传输介质引起激光测高仪回波能量衰减的机制;采用中纬度地区晴朗和霾雾天气下标准大气模式数据,计算了各衰减因素对1.064μm和0.86 μm激光的影响程度和大气斜程透射率随测高仪平台倾角的变化情况.为测高仪设计和对地观测应用提供了依据.
Abstract
Machanism of laser altimeter energy attenuation in atmosphere is analyzed, and using data of USA standard atmospheric mode middle latitude zone in fine and foggy days, slantwise transmissivities of 1.064μm and 0.86 μm relating to the obliquity of altimeter platform are presented. Qualitative analysis of echo signal width extension from atmosphere transfer medium is given. These benefit the design and observation appication of laser altimeter.
