Research on EMC Evaluation and Management Method Based on Time-Frequency Domain and Complex Network Modeling Analysis

This paper proposes an electromagnetic compatibility (EMC) evaluation and management method based on time-frequency domain analysis and complex networks, which can be used to evaluate the EMC of complex systems with multiple frequency equipment and provide recommendations for electromagnetic management methods. First, time-frequency domain processing methods are used to process electromagnetic environment (EME) data or conduct time-frequency domain simulation analysis on the equipment installed on the platform in typical working modes to sort out its time-frequency characteristics. Secondly, combining the application of complex network theory in the field of EMC, and taking into account the interference situation between equipment in the time-frequency domain, an overall EMC evaluation is conducted, and corresponding management method suggestions are given based on the evaluation results. Finally, through simulation analysis of the example, the method proposed in this paper can better evaluate the EMC of complex platforms or systems, and reduce the impact on electromagnetic spectrum resources and equipment utilization during EMC management.
