C波段双波束卫星接收天线及高效双模双波束馈源系统

C Band Dual Beam Satellite Receiver Antenna and High Efficiency Dual Mode Feeding Source System

本文采用偏置馈源口径场技术从理论上分析了偏置波束场型和增益,研究和计算了慧形象差影响所引起的增益损失。研制出的双波束馈源系统,可用于任意前馈卫星站的改造;3m双波束卫星接收天线增益高、副瓣低、噪声小。

Adopted the bias feeding source aperturefield technology, This paper analyses theoretically the bias beam field type and gain, studies and calculates the loss of gain caused by coma aberration. The dual beam feeding source system that is used on the transform of arbitrary feedforward satellite station and 3m dual beam satellite receiver antenna which the gain high, minor lobe small and noise low are developed.
