相位噪声对多普勒雷达接收机影响的分析

Analysis of Phase Noise Effects on Doppler Radar Receiver

针对相位噪声对多普勒雷达接收机的影响,从相位噪声的概念、成因、对多普勒雷达导引头的影响以及减小相位噪声对接收机影响的措施进行了探讨,重点研究了在导弹武器系统中,照射雷达发射机信号相位噪声对导弹导引头多普勒雷达接收机的影响。

In order to analyze the effects of phase noise on Doppler radar receiver, the concept and the causes of phase noise are described respectively and then its influence on Doppler radar seeker and the measure for reducing the phase noise effects are analyzed. The emphasis is then put on the impact of the illumination radar transmitter signal phase noise to the seeker Doppler radar receiver.
