Architecture design and analysis of a shipboard electromagnetic environment topology modeling system

This study presents a topology-based modeling system for shipboard electromagnetic environment analysis. The system abstracts ship structures into topological spaces with shielding planes and classifies interference sources (internal/external/exogenous). Using matrix operations, it efficiently calculates multi-source interference propagation and field strength. Key modules include topology modeling, interference management, matrix computation, and visualization. Tests show the system accurately quantifies interference components (95.2 dBμV/m from internal sources) and identifies critical paths, achieving 15 dB interference reduction through shielding optimization with <0.1s simulation time. The method provides an efficient EMC (Electromagnetic Compatibility) analysis tool for naval applications.
