Abstract
In order to solve the problem that the satellite with large reflector antenna cannot directly verify the electromagnetic compatibility between the antenna and the satellite, a satellite system-level semi-physical verification technology for electromagnetic compatibility is studied. The electromagnetic compatibility analysis between the large antenna and the satellite is carried out by the model hierarchical method, and the modeling method and analysis method are proposed. The equivalent verification system is designed. In the state of payload transmitting, the system can verify the influence of electromagnetic radiation on the satellite body after passing through the reflector antenna. Moreover, the influence of the electromagnetic radiation from the satellite body on the receiving state of the payload through the reflector antenna can also be verified. The arbitrary waveform generator can realize the verification test for the actual satellite signal form, while the two-dimensional automatic control antenna scanning frame can realize the scanning test in twodimensional space. The effectiveness of the method and technology was proved by a satellite test.
