Abstract针对高频段大口径全向可动射电望远镜QTT对电性能的高要求,必须降低风扰动对天线的影响.本文分析了QTT台址地形地貌以及风场分布的特点,提出了一种主动降低天线所在区域风速的QTT台址风场分布调控技术方案,进一步搭建了用于QTT台址风场分布调控微缩模型的等效风场试验,通过试验数据分析,确定了QTT风场分布调控技术方案的可行性,并初步给出了经风场调控后,风速显著降低的区域范围以及风速降低的幅度,为QTT台址风场分布的调控提供了技术依据,从而可大大增加射电望远镜的有效观测时间.
Other AbstractThe effect of wind gust on the large reflector antenna is one of the main factors that can affect the antenna performance and therefore, this effect must be minimized to meet the strict performance requirement in the world largest steerable telescope, which is QiTai Telescope (QTT). In this paper, the characteristics of the topography as well as the wind distribution around QTT site have been analyzed and consequently, a technology for improving the wind distribution in an active way has been proposed. Additionally, an equivalent wind distribution test rig for the proposed technology has been built in the lab and the corresponding experiment has been carried out. The experimental data indicated that the proposed technology was a promising tool for regulating the wind distribution for the large reflector antenna and it was found that the proposed technology can significantly reduce the wind speed as well as the wind impact range after the wind regulation has been given in the test. The results in this paper has provided a solid foundation for the regulation of the wind distribution of the QTT site.
