| Abstract: | The article mainly focuses on measurement of transmission attenuation of radio signal for electromagnetic environment in 80m radio telescope of Urumqi astronomical observatory. We reference to international GB/T14617.2-93 and Deygout model of transmission attenuation measurement to analysis and verify the model. We introduce the radio signal attenuation via hill transmission, combining with actual measurement methods to generate the feasible measurement model. |
