ITU-R REPORT SA.2166-2009 太空研究和射电天文学用大型天线的辐射方向图范例

The methodology and guidelines introduced in § 2 have been used to model the radiation patterns for large antennas used in deep space research and radio astronomy. These methods are described in detail in Recommendation ITU-R SA.1345 – Methods for predicting radiation patterns of large antennas used for space research and radio astronomy. In predicting the radiation pattern of the NASA’s deep space network (DSN) antenna, the latest version of a commercially available software package (GRASP9) has been used. For the radiation pattern of the radio astronomy antenna, an old version (GRASPC) of the same software has been used. The results illustrate the effect of various parameters on the model's predictions and the significance of various mechanical and design features.

ITU-R REPORT M.2141-2009 近距离甚高频(VHF)陆地移动无线电天线之间的隔离研究

This Report provides information on the determination of isolation for mobile radio antennas separated horizontally less than a few wavelengths in the 30 to 108 MHz bands. The study presents analytical and experimental isolation results for two antennas. The impact of isolation to the operation of radio systems and effect of the physical characteristics of the antenna platform are not studied.
