噪声参数是微波无线电领域中一个很重要的参数。一般来说,噪声是有害的,它干扰甚至淹没有用的信号,致使通信中断或者根本无法辨识目标信号。为了减小或衡量噪声对无线电通信的影响,以适应通信技术的发展,长期以来,人们对噪声所涉及问题进行了广泛研究,建立了一套衡量系统或器件噪声大小的参数体系。在这些参数中,噪声系数发挥举足轻重的作用。噪声系数分 Noise parameters are a very important parameter in the field of microwave radio. In general, noise is detrimental, it interferes with or even drown out useful signals, causing communication to be interrupted or not at all. In order to reduce or measure the impact of noise on radiocommunication in order to adapt to the development of communication technology, people have conducted extensive research on the problems involved in noise for a long time, and established a parameter system to measure the noise of the system or device. Among these parameters, the noise figure plays a decisive role. Noise factor score
