摘要
收带噪声功率是发射机的重要指标之一，其大小对系统性能有着重要影响，由于该指标的绝对数值比较小，一般情况下用仪器无法直接测量。本文根据工程经验总结出了几种不同的间接测量方法，并对其特性进行了分析说明，对工程研制和测试实践具有一定的帮助作用。
Receiving- band noise power is an importance guideline for a transmitter ,and its magnitude has an important influence on the system function. Because its absolute number is smaller, it cant be directly measured under general circumstances. According to engineering experience, several indirect measurement methods are summaried and their characteristics analysed in this paper. These measurement will be useful for engineering development and testing.
