Abstract:

Current frequency usage effectiveness evaluation suffers from insufficient methods and low accuracy, making it difficult to meet the needs of improving communication equipment performance and supporting personnel in mastering communication situations and making intelligent decisions. To address this, research on frequency usage effectiveness evaluation methods for communication systems is conducted. By constructing digital twin models of the natural environment, frequency-using equipment, and radio wave propagation environment, an intelligent matching algorithm for electromagnetic computation models is proposed. This enables a combined quantitative and qualitative evaluation of frequency usage effectiveness metrics, such as link performance, reconnaissance range, coverage, and interference capability of communication equipment in complex electromagnetic environments. Simulation applications based on typical test scenarios demonstrate that the proposed method can effectively support the selection and optimization of communication system solutions, provide technical means and tools for the intelligent evaluation of equipment communication frequency usage effectiveness, and enhance auxiliary support capabilities for mission planning and command decision-making.
