| 摘要: |
| 针对现有测控通信系统球面相控阵的波位设计方法难以满足大空域或全空域条件下的高效波位编排问题，从波束覆盖模型入手，研究了波束以及相邻波位在空域覆盖上的若干几何性质，并以此为基础提出了一种用于球面相控阵的波位设计方法。该方法以天顶方向为起始，自顶向下分圈实现设计，利用波位覆盖的几何性质以及最大化波束利用率准则计算各圈次的具体波位，从而实现全空域无缝覆盖条件下的高效波位编排。最后给出仿真示例说明波位设计方法的有效性。 |

| Abstract: |
| Considering that the current beam position design of phased array in TT&C and communication system is unable to arrange beam position covering the full airspace,the authors analyze the geometric properties for adjacent antennas beam and propose an algorithm for beam position arrangement covering the full airspace based on its coverage model.This top-to-bottom beam position arrangement algorithm starts from the zenith direction,and maximizes the beam utilization rate in each circle while guaranteeing the full airspace coverage.A numerical example is given to illustrate the effectiveness of the proposed algorithm. |
| Key words: TT&C and communication system spherical antennas phase array beam position arrangement full airspace coverage |
