摘要
参照反射面天线主波束效率估计的简易计算公式,对“神舟四号”(SZ-4)飞船辐射计天线的主波束效率进行了具体估算,给出了计算流程和计算结果.计算表明,该辐射计天线在6.6 GHz,19.35 GHz,23.8 GHz和37 GHz 4个频段上的波束效率分别为89％,91.24％,92.91％和94.87％,并经过了在轨飞行验证.
Based on a simple formula for calculating the main beam efficiency presented in Ref.[1], the main beam efficiency calculation is performed for multi-band microwave radiometer antenna boarded on 'SZ-4' spaceship. The calculation shows that the main beam efficiencies at 6.6, 19.35, 23.8 and 37 GHz are 89%, 91.24%, 92.91% and 94.87%, respectively.
