摘要
噪声是影响雷达接收机灵敏度的重要因素。本文通过讨论雷达接收机噪声的来源,分析并提出了集中降低雷达接收机内部和外部噪声的几种方法,具有一定的实际意义。
Noise is one of the most important factors that influence the sensitivity of the radar receiver. Several methods of debasing internal and external noise of the radar receiver are proposed in this paper by discussing the origin of the noise in the radar receiver. This method is proved to be useful.
