深空小规模天线上行组阵布局分析研究

针对天线上行组阵中阵元布局对远场功率合成增益影响的问题，给出了组阵地面布局的要求，包括阵元间最小距离、布局紧凑性、灵活性、可扩展性和经济性等。在此基础上对小规模组阵(阵元数3~36)布局进行了分析，设计了不同阵元时对应合成增益最高的布局方式。最后用计算机仿真各种布局情况下在月球量级远场目标点的功率合成增益，比较远场功率合成增益大小并总结了一些规律，结果表明各阵元的最优布局与理论分析相符。考虑组阵规模的可扩展性给出了16元阵、36元阵的最优布局，可为实际应用提供参考。

Analysis on the layout of small scale antenna uplink arraying for deep space

The requirements of the array layout is given to solve the problem of the effect of antenna layout to the far-field power combining gain in antenna uplink arraying,including the minimum distance between elements,the compactness,flexibility,scalability and economical of layout.The layout of small-scale array(3 ~36 array elements)is analyzed,and of the highest power gain of different array element is designed.Then,using computer simulate lunar-distance far-field power gain of different layouts,the gain value is compared and summed up some rules.The simulation results show that the optimal layout is consistent with theoretical analysis.considering the scalability of arraying scale, reference layout of 1 6 and 36 array elements is given.
