摘　　要：建立了月表环境下无线电波传播路径损耗的分段预测模型,并基于NI公司LabWindows/CVI软件平台开发了一套月表电波损耗可视化预测软件。该软件可实现三维的月表数字地形及收发信机位置实时显示,无线电波传播损耗动态预测,以及预测参数及结果的灵活管理。实测结果表明,该软件预测结果与实测数据吻合,操作简便且运行稳定,可用于辅助我国探月工程中月表通信系统的参数设计和性能评估,对于深空探测系统设计也具有一定的参考价值。A segmented prediction model for radio propagation loss over lunar surface was established.A new visualization prediction software of radio wave loss on lunar surface was developed based on the LabWindows/CVI development platform from NI.The software can realize real-time display 3D digital terrain of lunar surface and the location of transceiver,predict the loss of radio wave transmission dynamically,and manage the prediction parameters and results flexibly.The practical detection result shows that the prediction results of this software are very close to the deteted data,and the software works stable and is easy to use.So it＇ s very helpful for the parameters design and performance assessment for the lunar surface communication system in the next lunar exploration project of China and also has a reference value for design of the deep spacedetection systems.
