| Summary: | The reliability of data-link communication equipment in electromagnetic environment is a hot and difficult research topic in wireless communication and electronic countermeasures field. The maximum communication distance when the equipment “ lost-link” was taken as the reliability evaluation index of the data-link equipment, and the minimum received working signal intensity of data-link under different interference conditions was simulated through electromagnetic interference injection test. Therefore, the Friis transmission model was used to calculate the maximum communication distance of data-link communication equipment under different electromagnetic interference conditions. The lognormal distribution was used to fit the statistical distribution of the maximum communication distance under electromagnetic interference. The variation rule of distribution parameters with interference frequency and intensity was estimated based on multiple regression method, and the reliability model of data-link communication equipment based on degradation quantity distribution was constructed. Finally, the effectiveness of the proposed method is verified by a numerical example. The research results can provide theoretical reference for communication equipment configuration, communication success rate prediction and battlefield situation assessment in combat missions. |
