Description
Das Haiiptpatent j6j 354 betrifft ein Ver-. fahren zur Richtungsbestimmung unter Verwendung einer gerichteten rotierenden Strahlung, die in Abhängigkeit vom jeweiligen Azimut bestimmte Kennzeichen aussendet. Bei dem vorgeschlagenen Verfahren werden am Empfangsort sowohl die die einzelnen Winkelgrade der rotierenden Strahlung kontinuierlich markierenden Kennzeichen als auch der FeIdstärkeverlauf der rotierenden Strahlung direkt übereinander aufgeschrieben. Die Richtungskennzeichen werden sendeseitig von einer Scheibe abgetastet, die auf der gleichen Achse wie der sich dre-hendeRichtstrahler angeordnet ist und vorzugsweise einer besonderen, synchron mit der eigentlichen Richtstrahlung umlaufenden Hilfsstrahlung aufmoduliert. Die Kennzeichenscheil>e enthält die Gradeinteilung sowie die verschiedenen Gradzahlen in Form von lichtdurchlässigen Stellen. Die von einer normalen Abtastvorrichtung, beispielsweise einer Lichtquelle und Phptozelle, gelieferten Impulse werden dann empf angsseitig auf einem Registrierstreifen nach dem Hellschreibprinzip aufgezeichnet.The shark patent j6j 354 relates to an association. drive to determine the direction using directional rotating radiation that emits certain indicators depending on the respective azimuth. In the proposed method, both the characteristics continuously marking the individual angular degrees of the rotating radiation and the field strength profile of the rotating radiation are written directly one above the other at the receiving location. The directional indicators are scanned on the transmission side by a disk which is arranged on the same axis as the rotating directional emitter and preferably modulates a special auxiliary radiation that circulates synchronously with the actual directional radiation. The license plate> e contains the graduation and the various degrees in the form of translucent places. The pulses supplied by a normal scanning device, for example a light source and phptocell, are then recorded on the receiving side on a recording strip according to the light writing principle.
Dieses Aufzeichnungsverfahren soll nun nach dem Vorschlag der vorliegenden Erfindung zur Festlegung einer oder mehrerer bestimmter Richtungen weitergebildet werden. Wie in Abb. 1 dargestellt ist, kann ein Flugzeug F beispielsweise die Aufgabe erhalten, ein Ziel Z von einem Standort D aus unter einem ganz bestimmten Winkel anzufliegen. Befindet sich im Punkt D ein rotierendes Funkfeuer nach dem Hauptpatent, so weist das Ziel Z, von dem Funkfeuer aus gesehen, das Azimut α auf. Das Flugzeug braucht nunmehr seinen Kurs nur so zu wählen, daß auf der Schreibfläche stets der Winkel α erscheint. Um dem Flugzeugführer das dauernde Ablesen dieses Winkels zu erleichtern, wird gemäß vorliegender Erfindung vorgeschlagen, mit der senderseitigen Abtastvorrichtung (Kennzeichenscheibe, Photozelle) zusammenarbeitende Mittel vorzusehen, die der Kennzeichenstrahlung beim Durchlaufen des Richtdiagramms (Leitstrahldiagramm) durch die gewünschte Richtung besonders markante Kennzeichen aufzudrücken. 1According to the proposal of the present invention, this recording method is now to be developed further in order to define one or more specific directions. As shown in FIG. 1, an aircraft F can, for example, be given the task of approaching a target Z from a location D at a very specific angle. If there is a rotating radio beacon according to the main patent at point D , then the target Z, as seen from the radio beacon, has the azimuth α. The aircraft now only needs to choose its course in such a way that the angle α always appears on the writing surface. In order to make it easier for the pilot to continuously read this angle, it is proposed according to the present invention to provide means that work together with the transmitter-side scanning device (identification disk, photocell), which imprint particularly distinctive identifiers on the identification radiation when it passes through the directional diagram (guide ray diagram) through the desired direction. 1
s° In Abb. 2 ist ein Ausführungsbeispiel für den Ernndungsgedanken dargestellt. K stellt die synchron mit der Senderstrahlung sich drehende Ksnnzeichenscheibe dar, auf der die Lichtspalte von der Vorrichtung A abgetastet werden. Auf dem L'mfang dieser Kennzeichenscheibe befindet sich ein Nocken M, der einmal pro Umdrehung der Kennzeichenscheil>e eine Kontakteinrichtung betätigt. Während der Schaltzeit dieser Kontakteinrichtung wird beispielsweise ein Impuls bestimmter Länge erzeugt, der dann der Kennzeichenstrahlung aufgedrückt wird. L"m diesen zusätzlichen Impuls jeweils im gewünschten Azimut dem Kennzeichendiagramm aufzudrücken, ist die Kontaktanordnung B, die sich beispielsweise auf einer Grundplatte C befindet, konzentrisch zur Kennzeichenscheibe· verstellbar. Diese Verstellbarkeit ist in Abb. 2 durch die Schlitze 6" angedeutet. s ° In Fig. 2 an embodiment for the Ernndungs thought is shown. K represents the symbol disk rotating synchronously with the transmitter radiation, on which the light gaps are scanned by the device A. On the circumference of this license plate there is a cam M which actuates a contact device once per revolution of the license plate. During the switching time of this contact device, a pulse of a certain length is generated, for example, which is then impressed on the license plate radiation. If this additional impulse is to be applied to the identification diagram in the desired azimuth, the contact arrangement B, which is for example on a base plate C, can be adjusted concentrically to the identification disk. This adjustability is indicated in Fig. 2 by the slots 6 ".
In Abb. 3 ist ein Registrierstreifen E dargestellt, auf dem außer dem Feldstärkeverlauf F und der die Winkellage aiigel>enden Gradeinteilung der zusätzliche Impuls H eingezeichnet ist. Der Flugzeugführer, der das Ziel Z auf direktem Wege anfliegen soll, hat nunmehr lediglich die Lage des Markierungssignals H zu der Xullrichtung des Feldstärkeverlaufs zu beobachten.In Fig. 3, a recording strip E is shown, on which, in addition to the field strength curve F and the graduation that ends the angular position, the additional pulse H is drawn. The pilot who is supposed to approach the target Z in a direct way now only has to observe the position of the marking signal H in relation to the zero direction of the field strength curve.
Der erfindungsgemäße Vorschlag hat gegenüber anderen mit Funkfeuern arbeitenden Zielansteuerungsmethoden, die es ermöglichen, ein bestimmtes Ziel, unabhängig von einer auftretenden Windabtrift, unter einem genau vorbestimmten Winkel geradlinig anzusteuern, den Vorteil, daß eine Abweichung von diesem Kurs in besonders sinnfälliger Weise angezeigt und daher leicht erkannt wird.The proposal according to the invention has over other working with radio beacons Target control methods that make it possible to a specific target, regardless of a wind drift occurring, under one to drive exactly predetermined angle in a straight line, the advantage that a deviation is indicated by this course in a particularly obvious way and is therefore easily recognized.
