Description
Anordnung zum Richtempfang von kurzen Wellen. Zum Goniometerempfang von normal polarisierten Wellen, d. h. von Wellen, deren magnetische Feldstärke parallel zur Erdoberfläche verläuft, «erden bekanntlich zwei zueinander senkrecht stehende Rahmen, deren Fläche senkrecht zur Erdoberfläche steht, verwendet. Es .ist anzunehmen, daß bei kurzen Wellen eine Drehung der Polarisationsebene eintritt, so daß dann auch mit einer Komponente der Feldstärke zu rechnen ist, die normal zur Erdoberfläche steht. Für diesen Fall reicht- die Anordnung mit zwei Rahmen nicht mehr aus, um das Maximum des Empfangs zu erzielen. Gemäß der Er-. findung wird dies durch eine Anordnung möglich, bei der man außer den zwei Rahmen mit senkrechter Windungsfläche einen dritten mit horizontaler Windungsfläche verwendet.Arrangement for directional reception of short waves. To the goniometer reception of normally polarized waves, d. H. of waves, their magnetic field strength runs parallel to the surface of the earth, "as is well known, two earths perpendicular to each other standing frames, the surface of which is perpendicular to the earth's surface, is used. It is to assume that with short waves a rotation of the plane of polarization occurs, so that a component of the field strength can then also be expected which is normal stands to the surface of the earth. In this case, the arrangement with two frames is not enough more in order to achieve the maximum reception. According to the er-. finding becomes this possible through an arrangement in which, in addition to the two frames, with vertical Winding surface used a third with a horizontal winding surface.
Zu den Feldspulen im Goniometer müssen dann noch eine oder zwei horizontale hinzutreten, und die Drehspule muß außer um die vertikale Achse noch um eine horizontale Achse drehbar gemacht werden. Man kann auch, um den horizontalen Rahmeneffekt zu empfangen, noch eine besondere Kopplungsspule verwenden, die mit der Drehspule des Goniometers in Serie liegt.One or two horizontal coils must then be added to the field coils in the goniometer step in, and the moving coil must be around a horizontal axis in addition to the vertical axis Axis can be made rotatable. One can also get the horizontal frame effect too received, still use a special coupling coil that is connected to the moving coil of the Goniometers in series.
