Abstract

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.
