Description

Rahmensystem zur Peilung beliebig polarisierter Wellen Zur Behebung von Fehlpeilungen, die durch die Raumwelle verursacht werden und besonders während der Dämmerung auftreten, sind Rahmensysteme bekannt, die zwei vertikale Drehrahmen verwenden, die in einer Ebene liegen und um eine vertikale Achse drehbar sind. Diese Anordnungen bringen den Nachteil mit sich, daß die Peilminima sehr breit werden.Frame system for finding arbitrarily polarized waves of incorrect bearings caused by the sky wave and especially during occur at dusk, frame systems are known that have two vertical rotating frames use that lie in one plane and can be rotated about a vertical axis. These Arrangements have the disadvantage that the bearing minima become very wide.

Vorliegende Erfindung betrifft eine neue Rahmenanordnung, die ebenfalls Fehlpeilungen vermeidet und gegenüber den bekannten Anordnungen den Vorteil bringt, daß die Minima erheblich schärfer werden.The present invention relates to a new frame assembly that also Avoids incorrect bearings and has the advantage over the known arrangements, that the minima are considerably sharper.

Die neue Anordnung verwendet in bekannter Weise zwei elektrisch gegeneinandergeschaltete Peilrahmen, die um eine gemeinsame Achse .drehbar sind. Die Flächen der beiden Rahmen liegen jedoch im Gegensatz zu den bekannten Anordnungen nicht in einer Ebene, sondern sie liegen in zwei verschiedenen, zueinander parallelen Ebenen.The new arrangement uses two electrically connected against each other in a known manner Monitoring frames that can be rotated around a common axis. The faces of the two frames However, in contrast to the known arrangements, they are not in one plane, but they lie in two different, mutually parallel planes.

In der Zeichnung ist die neue Anordnung in zwei Rissen abgebildet, wobei im Grundriß die Charakteristik des Rahmensystems für die Komponenten der Raumwelle und für die Bodenwelle eingezeichnet ist. Der Betrachtung wurde der magnetische Vektor des Peilfeldes zugrunde gelegt, wobei der Vektor der Raumwelle in drei Komponenten zerlegt wurde. Die Komponente HF liegt horizontal und in der Fortpflanzungsrichtung der Raumwelle, die Komponente HV ist senkrecht nach oben gerichtet, und die Komponente HH ist horizontal und gleichzeitig senkrecht zu der durch die beiden ersteren Komponenten gebildeten Ebene. Die von diesen Komponenten sowie von dem magnetischen Vektor HB der Bodenwelle in dem Rahmensystem induzierten Spannungen sind in der Zeichnung mit UF, UH und UB bezeichnet. Die Komponente UV induziert in keiner Lage des Rahmensystems Spannung. Die Abbildung zeigt, daß in zwei um i8o ° versetzten Richtungen, die senkrecht zur Verbindungslinie der Rahmen liegen, von keiner Komponente des Peilstrahles Spannung induziert wird. Man wird daher unabhängig vom Polarisationszustand der Wellen in den genannten Richtungen ein scharfes Minimum erhalten, wobei keine Fehlpeilungen auftreten können.In the drawing, the new arrangement is shown in two cracks, with the floor plan showing the characteristics of the frame system for the components of the sky wave and for the ground wave. The observation was based on the magnetic vector of the bearing field, whereby the vector of the sky wave was broken down into three components. The component HF lies horizontally and in the direction of propagation of the space wave, the component HV is directed vertically upwards, and the component HH is horizontal and at the same time perpendicular to the plane formed by the first two components. The voltages induced by these components as well as by the magnetic vector HB of the bump in the frame system are designated in the drawing with UF, UH and UB . The UV component does not induce tension in any position of the frame system. The figure shows that in two directions offset by 180 °, which are perpendicular to the connecting line of the frames, no voltage is induced by any component of the bearing beam. Regardless of the polarization state of the waves, a sharp minimum will therefore be obtained in the directions mentioned, with no misdirections being able to occur.

Die rechnerische Ableitung der Charakteristik ergibt für die Bodenwelle und für die horizontale Komponente der Raumwelle eine Funktion vom cos des halben Rahmendrehwinkels und ergibt somit eine sehr starke Schärfe des Minimums.The arithmetic derivation of the characteristic results for the bump and for the horizontal component of the sky wave a function of cos of half Frame rotation angle and thus results in a very strong sharpness of the minimum.

Außer der gezeigten Anordnung sind auch Kombinationen von übereinanderliegenden Rahmen möglich, die die einleitend genannten Anforderungen erfüllen. Weiterhin ist es möglich, die Rahmen nicht um eine gemeinsame Achse, sondern um getrennte Achsen zu drehen.In addition to the arrangement shown, there are also combinations of one above the other Framework possible that meet the requirements mentioned in the introduction. Furthermore is it is possible to move the frames around separate axes rather than a common axis to turn.

Besonders vorteilhaft ist die Peilung mit den genannten Rahmensystemen bei Kurzwellenpeilung über sehr große Entfernungen, wo im wesentlichen nur mehr die Raumwelle gepeilt wird. .Bearing with the frame systems mentioned is particularly advantageous with short-wave direction finding over very large distances, where essentially only more the sky wave is sounded. .
