摘要
探讨宽波束天线噪声温度的计算方法及噪声温度对系统灵敏度的影响 ;提出天线自身噪声源、天线自身噪声温度、天线直流电阻、天线交流阻抗等概念 ,给出自身噪声温度的计算公式 ;对典型的
The calculation of thenoise temperatureof a wide beam antenna is researched using total field components. The Concepts of the self-noise source,the self-noise temperature,the DC resistance and the AC impedance are proposed for an antenna.The noise temperature of a GPS receiving antenna is calculated.
