频率源的相位噪声对雷达系统性能的影响

摘要

Frequency source is the important component of radar system .This paper discusses the influence factors of local oscillation phase noise on the radar system from the concept and cause of phase noise ,and educes logical phase noise index parameters on the premise of meeting the system requirements .%频率源是雷达系统的重要组成部分，从相位噪声概念、成因讨论了本振相位噪声对雷达系统的影响因素，并得出在满足系统要求前提下合理的相位噪声指标参数。
