This patent only establishes a model based on the three-dimensional structure of the spacecraft in the electromagnetic compatibility analysis, and does not perform modeling and simulation according to the actual layout of the radio frequency equipment. Therefore, the safety margin in the final radio frequency analysis results is only a simple estimation result. This is not accurate enough for the electromagnetic interference analysis results of radio frequency equipment on the spacecraft's extravehicular equipment.

The invention relates to an electromagnetic compatibility analysis method for high-power radio frequency equipment in a manned spacecraft. The electromagnetic compatibility analysis method comprises the following steps: a, determining the frequency of the high-power radio frequency equipment and whether the linear combination frequency of the high-power radio frequency equipment and other radio frequency equipment falls into the bandwidth of receiving equipment or not; b, establishing a coupling equation between each antenna and the spacecraft to obtain isolation between the antennas; c, calculating the intensity of a signal arriving at the radio frequency receiving equipment; d, calculating the safety margin between the high-power radio frequency equipment and each radio frequency receiving equipment; e, establishing a simulation model of electric field intensity radiation distribution; f, establishing an electromagnetic field equation between the high-power radio frequency equipmentantenna and the spacecraft; and g, obtaining an electric field intensity distribution diagram of the high-power radio frequency equipment, and respectively judging the influence of the electric fieldof the high-power radio frequency equipment on equipment outside the spacecraft cabin and personnel in the cabin. According to the analysis method, the real influence of the electromagnetic field of the high-power radio frequency equipment on spacecraft equipment and astronauts can be reflected through simulation analysis.
Description
technical field [0001] The invention relates to the field of electromagnetic compatibility analysis, in particular to an electromagnetic compatibility analysis method for high-power radio frequency equipment in manned spacecraft. Background technique [0002] In the past manned spacecraft, radio frequency equipment is mainly used for data, image and voice communication between the sky and the earth, and the transmission power of radio frequency equipment is generally in the order of several watts or tens of watts. With the development of lunar and other deep space exploration missions, the data rate that needs to be transmitted between the sky and the earth is increasing, such as high-definition images, high-speed test data, etc. Correspondingly, the transmission power of space-to-earth wireless communication equipment is greatly increased. At the same time, space application loads need to be equipped with high-power transmission equipment due to functional requirements, suc...
