摘　　要：文章给出了基于浮空气球的全面验证空间太阳能电站微波能量传输工作模式、功能和效率的垂直验证系统,该系统还可用于验证临近空间浮空平台微波输能相关关键技术。系统中发射天线为近似高斯分布的平面微带天线阵列。利用理论传输公式和辐射场积分方法分别计算了波束收集效率,本系统的波束收集效率可达94%。与均匀分布的计算结果相比,本系统的波束收集效率得到了很好的改善。This paper presents a microwave power transmission（ MPT） vertical demonstration system based on balloon platform. The system comprehensively simulates the operating mode and validates the functions and efficiency of microwave power transmission technologies for SSPS（ Space Solar Power Station）. The system can also simulate key technologies in MPT for near-space platform energy supply. The transmitting antenna array is a planar microstrip antenna array with quasiGaussian distribution. The beam collecting efficiency of this system is about 94%. The scheme is analyzed by theoretical transmission equation and radiation field integral method respectively. Comparing with uniform distribution,the beam collecting efficiency in this system is well enhanced.
