Abstract

The invention provides a compensation method for the attenuation of cloud, fog and rain in a satellite communication. The method comprises the following steps: 1, respectively calculating a cloud andfog attenuation value and a rain attenuation value on a satellite-earth link in the satellite communication; and 2, compensating the cloud attenuation value and the rain attenuation value, adopting fixed compensation on a downlink of the satellite communication, and adopting dynamic rain attenuation compensation on an uplink of the satellite communication in real time. According to the method, when the cloud and fog attenuation value and the rain attenuation value are compensated, fixed compensation is adopted in a downlink of satellite communication, dynamic rain attenuation compensation is adopted in an uplink of the satellite communication in real time, attenuation of cloud, fog and rain can be compensated, satellite control can be simplified, compensation errors can be effectively reduced, and reliable transmission of information is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a compensation method for attenuation of clouds, fog and rain in satellite communication, in particular to a compensation method for attenuation of clouds, fog and rain in Ka-band satellite communication. Background technique [0002] In the design of satellite-to-Earth links, engineers are often concerned with the amount of rainfall at the location of the ground station. They can then calculate the appropriate link margin and ensure a stable connection of the link under certain climatic conditions. However, most engineers do not consider the effects of clouds, rain and fog on radio wave propagation. This effect has become a forgotten area of ​​SATCOM satellite-Earth link design. Contents of the invention [0003] The invention provides a compensation method for attenuation of cloud, fog and rain in satellite communication, which is used for compensating the at...
