摘要

研究了低地球轨道卫星l波段共形天线阵的增益噪声温度比(G/T)。基于地球静止赤道轨道(GEO)卫星与低轨道卫星的可见角度，通过开关相关天线元件和波束形成来实现优化的G/T性能。在0°~ 90°θ范围内，波束形成阵列的G/T达到- 19 dB/K以上。

G/T Study for Conformal Antenna Array

The gain-to-noise-temperature (G/T) of a seven antenna elements based L-band conformal antenna array for a low earth orbit (LEO) satellite is studied. The optimized G/T performance is achieved by switching on and off the related antenna elements and beamforming based on the visible angle of a geostationary equatorial orbit (GEO) satellite from a LEO satellite. The G/T of the array with beamforming is achieved above −19 dB/K for θ range from 0° to 90°.
