英文摘要	Cirrus clouds are widespread in the atmosphere. The inhomogeneous distribution of ice crystals in the cirrus cloud has a serious impact on laser communication with high accuracy requirements. This study improves the traditional model and proposes inhomogeneous plane-parallel model for laser transmission in different atmospheric environments. In the model we consider the vertical variation of ice particle density. Four examples demonstrate direct transmission and first-order scattering power in four different environments (rural, city, ocean and desert) after a 1.55 mu m laser transmits through inhomogeneous cirrus clouds. The results show that the closer the receiving terminal is to the ground, the greater the attenuation of the laser by atmospheric molecules and aerosols. When the visibility is 5km, the attenuation in the city is greater than in the rural. When the aircraft is in the cloud, inhomogeneous cirrus clouds cause direct transmission and first-order scattering to be different between the cloud top and the cloud base. This study will provide a more accurate theoretical model for the application of laser communication to aircraft and serve as a guideline for further laser communication experiments and network technology research.
