摘　　要：星载多波束天线具有广阔的应用前景,尤其适合应用于低轨卫星系统。讨论了星载多波束天线点波束设计的方法,为平衡点波束各覆盖区域的接收增益,借鉴最优化理论思想,提出了一种点波束设计的方法,以全球星系统为例进行分析,结果表明该方法较典型的点波束设计方法具有更高的满意度。Multi -beam antenna is widely used in low earth orbit（LEO） satellite systems. Spot -beam de- sign of on - board multi - beam antenna is discussed, an optimized method adopting optimization theory for spot - beam design is proposed to balance the receiving gain of each spot - beam covering area, analysis of the optimized method for Globalstar system is given, and higher satisfaction of the p proved.
