基于ITU—R P.368的中波地波场强预测软件实现

AM Ground Wave Field Strength Prediction Software Based on ITU-R P.368

中波覆盖研究是广电无线发射领域易被忽视的问题,国内有关中波传播理论研究的可参阅资料不是很丰富,我国现行中波覆盖标准仍然是1980年发行的GB2017-80《中波广播网覆盖技术》。本文是作者在系统学习研究中波传播理论的基础上,应工作需要,在Web GIS(天地图)平台上,编制完成中波地波场强预测软件的经验总结。

Medium-wave coverage problem is easy to be neglected in wireless radio and television broadcasting. In China, the related literature of wave propagation is insufficient. The wave coverage standard of China is issued in 1980, which is GB2017-80 ＂Medium-wave Broadcasting Network Coverage Technology＂. We study systematically on the wave propagation theory. This paper proposes a kind of software for AM ground wave field strength prediction on Web GIS.
