摘要
介绍影响微波辐射计灵敏度的两个主要因素 :系统增益和本机噪声。围绕这两个影响因素 ,介绍提高辐射测量灵敏度所采取的两种方法 :电的或人工的方法以及软件处理的方法。最后讨论微波辐射计灵敏度研究中存在的问题 。
The Systemic gain and receiver noise,as two main influencing factors of radiometer sensitivity,are described in this paper.Then,according to these two factors,the electric (or artificial)method and software processing method are introduced detailedly which are used to improve the radiometer sensitivity.Finally,the presented questions in the research work to improve the microwave radiometer sensitivity are discussed,and the future development in improving microwave radiometer sensitivity are also mentioned.
