ITU-R P.2001模型在FAST宁静区的适用性研究

Applicability of ITU-R P.2001 recommendation in the FAST radio quiet zone

摘要: 为验证、研究ITU-R P.2001模型在FAST宁静区的适用性，首先系统分析了该模型所考虑的传播机理，给出了预测流程；其次，在FAST宁静区选择了多个公众移动基站，在周边开展外场测试并采集测试数据；最后，对比分析了实地测量值与模型预测值，结果表明预测结果与实测结果之间呈现较为相符的总体趋势，两者间的均方根误差为7.93 dB。上述研究结果可为FAST宁静区无线电设备电磁兼容分析、ITU-R P.2001预测模型区域化本地化研究及应用提供理论参考。

Abstract: To verify the applicability of the ITU-R P.2001 model in the Five-hundred-meter Aperture Spherical radio Telescope (FAST) radio quiet zone, we first analyze the propagation mechanism of the ITU-R P.2001 model and list the prediction process. In addition, we select multiple public mobile base stations in the FAST quiet area, finish outside testing, and collect test data. In the end, we compare the measured values with the predicted values of the ITU-R P.2001 model. The results show that there is a generally consistent trend between the predicted and the measured results, and the root mean square error is 7.93 dB. The above research results can provide a theoretical reference for electromagnetic compatibility analysis of FAST peripheral radio equipment and regional localization research and application of the ITU-R P.2001 model.
