中文摘要：

为适应全空域导航星座的管理需求,提出了一种全空域球面数字多波束天线系统的方案,在全空域内同时形成多个波束,实现同时多目标测控。针对球面阵列天线波束控制问题,提出了“波束滑动扫描”算法,研究了球面阵波束交叉过渡、功率增强的方法。通过对波束方向图的仿真分析,验证了波束控制方法的可行性和正确性。

英文摘要：

In order to adapt to the requirements of navigation constellation management in hemispherical coverage,a solution of spherical digital multi-beam antenna system in hemispherical coverage is proposed. The multiple beams are formed in hemispherical coverage to realize simultaneous multi-target navigation. Aiming at the control of spherical array antennas beam, this paper proposes a ＂beam slip scanning＂ algorithm,and studies the method of beam cross-transition and power enhancement.The feasibility and correctness of the beam control method is verified by the simulation analysis of beam pattern.
