| 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. |
