Abstract
A direction finder antenna system and method are described. The direction finder antenna system comprises a rotatable platform comprising at least two antenna units at selected distance between them, a motor configured for moving the rotatable platform at a motion pattern, and a signal collection circuit configured for receiving data on signal portions collected by said at least two antenna units with respect to different angular positions of said at least two antenna units. The signal collection circuit generates output data indicative of direction of origin of collected signal.
