具有漂移的发射机频率的雷达系统（例如采用磁控管发射机的雷达系统）通常使用自动频率控制系统来保持接收机下变频设置调谐到发射频率。本文提出了一种方法，将自动频率控制信息的测量影响改变接收机频率下变频设置，如相位测量，以获得在活动领域的变化。
Radar systems with a drifting transmitter frequency (such as those employing magnetron transmitters) typically use an Automatic Frequency Control system to keep the receiver down-conversion settings tuned to the transmitted frequency. This paper presents a method to incorporate the Automated Frequency Control information in measurements affected by changing receiver frequency down-conversion settings, such as phase measurements to obtain change in refractivity fields.
