基于ITU-R P.1546-3建议书的一种电波传播修正模型
Modified Model for Radiowave Propagation based on ITU Recommendation P.1546-3
ITU-R P.1546-3建议书（以下简称1546建议书）是国际电信联盟提供的地面业务点对面无线电传播预测的方法。由于1546建议书规定发射天线高度超过3000米时失效，本文提出一种等效发射源的近似分析方案，并给出了这种等效发射源方法与直接应用1546模型之间的误差的经验公式，使得当发射天线高度超过3000米时，仍可以使用1546建议书的方法进行无线电波传播的场强预测。
Recommendation 1546(Recommendation ITU-R 1546.3) is a way for ground point-to-area radiowave propagation prediction which is provided by International Telecommunication Union. Since Recommendation 1546 would be invalid when the height of transmit antenna is above 3000 meters, an equivalent analysis precept and its experiential error formula are raised. As a result, Recommendation 1546 could be used for radiowave propagation field strength prediction when the height of transmit antenna is above 3000 meters.
