摘要

Abstract The influence of the incidental frequency modulation of direction-finding signal on the direction-finding accuracy of aerodrome automatic direction finders is analyzed. It is shown that the direction-finding accuracy is the most greatly influenced by the incidental frequency modulation caused by the reflection of the onboard radio station signal from the helicopter blades. Methods for eliminating errors caused by incidental frequency modulation are proposed.
