论述了厘米波段天线背景噪声电平测量的重要作用、基本条件和要求。介绍了其测量系统灵敏度的估值方法,及在工程上用定标的技术参数计算灵敏度的公式。测量结果表明理论计算和测量数据处理结果符合得很好,证明该测量系统的灵敏度估算、工程计算方法及实施的测量方法是科学的、严密的,测量的数据是真实的、准确的。同时给出系统测量原理方框图,定标的技术参数和技术路线等。并对测量结果进行了分析和讨论。

The paper discusses the importance of measuring background -noise's level of centimeter wave-band on antenna and its basical technical condition and request. It also introduces the method to estimate the maximum sensitivity of antenna receive and measure system and the formula which calculates the sensitivity with technicals parameter the calibration in engineering applications. The measurement results show that the data analysis results of actual measurement are well fitted to theoretical calculation. This proves that it is scientific and rigorous that the estimation of sensitivity, the calculation method in engineering application and the measure method, This also proves that the measure results are real and precise. At the same time the paper gives the theory frame figure of measuring in background -noises temperature, the technical parameter of Calibration and its technical route etc. In this paper, we analysis and discuss measurement results, too.
