摘要
在微波辐射计的应用中,系统增益长期稳定性是一个重要设计指标。本文给出了一种噪声相加比较式微波辐射计体制。通过实验证明此体制具有测量的准确度与系统的增益变化无关、输出与接收机噪声温度无关的优点。
Due to the restriction of the calibration source and the influence of system gain and receiver noise fluctuation,the long-term stability,high sensitivity and high absolute accuracy of radiometer are not well solved.In this dissertation,a new type Microwave Radiometer which can prevent the influence of system gain and receiver noise fluctuation is introduced.
