EMI Analysis among LEO Satellites Based on Space Conjunction Theory

Space target collision theory is a new effective evaluation method based on random analysis and collision probability, which is one of the front-line defense methods to protect space active satellites. As the number of devices in space that emit electromagnetic signals surges, congestion has emerged in the space electromagnetic environment, which can be understood as “electromagnetic spectrum collision” between space electronic devices. This paper analyzes and demonstrates the application of space target collision model in the research of electromagnetic interference of satellite equipment; briefly reviewed the theoretical model of physical collision of space objects; analyzed the application of space physics collision theory to electromagnetic interference of satellite equipment; By means of numerical simulation and data analysis, a dynamic analysis method of electromagnetic radiation coverage based on spatial correlation theory is presented. The main purpose of this paper is to introduce the space target collision theory in the field of system level EMC evaluation and improve the electromagnetic interference evaluation technology in system modeling and simulation.
