Research on Adaptability Evaluation of Satellite Communication in Complex Electromagnetic Environment

According to the link characteristics of satellite communication, this paper clarifies the principles of selecting the evaluation index of the satellite communication complex electromagnetic environment adaptability before the adaptability evaluation, constructs the satellite communication electromagnetic environment evaluation index system, and proposes the evaluation method of the complex electromagnetic environment adaptability. With the development of communication satellite technology and the massive launch of communication satellites, Communication satellites are facing increasingly complex electromagnetic environments caused by intentional and unintentional interference, this complex spatial electromagnetic environment composed of a large number of electromagnetic signals with complex patterns, densely overlapping, and dynamic overlapping forms a severe test for the normal operation of communication satellites. Therefore, how to improve the adaptability of complex electromagnetic environment and the level of scientific evaluation, has become a key issue that needs to be solved urgently for communication satellites.
