Description
Sendeanordnung zur Erzielung von Kurslinien gemäß Patent 577 350 Im Hauptpatent wird: vorgeschlagen, zur Erzielung von Kurslinien mittels verschieden gerichteter, abwechselnd ausgesandter Strahlungen (z. B. nach der a-n-Methode) eine Erregerantenne gleichmäßig durch einen Hochfrequenzerzeuger zu speisen und Reflektoren anzuordnen, die getastet werden. Im einfachsten Falle sind einfache Dipole vorhanden. Die Tastung erfolgt meist nicht mit dem Kennzeichen a-n, sondern mit Punkten und Strichen. Bei praktischen Versuchen hat sich ergeben, daß der Dauerstrich nur dann sauber und konstant ist, wenn dafür gesorgt ist, daß beim Übergang von einem zum anderen Zeichen keine Energieabnahme auftritt. Man hat zur Lösung dieser Aufgabe bereits komplizierte Relaisanordnungen vorgeschlagen, die dafür sorgen sollen, daß das Wirksamwerden des einen Reflektors zeitlich genau mit dem Unwirksamwerden des anderen Reflektors zusammenfällt. Die- sich hierbei ergebenden Tastanordnungen sind außerordentlich kompliziert, und vor allen Dingen müssen sie peinlich genau gewartet werden, damit sich nicht bei längerem Betrieb der Fehler, der beseitigt werden soll, wieder einstellt. Es ist noch zu berücksichtigen, daß ein zu frühes Wirksamwerden des zweiten Reflektors ebenfalls den Dauerstrich unwirksam macht. Es ist leicht einzusehen, daß die hier bestehende Aufgabe keineswegs so einfach auf diese Weise erfüllt werden kann.Transmitter arrangement for the achievement of course lines according to patent 577 350 In the main patent it is proposed to feed an excitation antenna evenly through a high frequency generator and to arrange reflectors to achieve course lines by means of differently directed, alternately emitted radiation (e.g. according to the an method) be keyed. In the simplest case, there are simple dipoles. The keying is usually not done with the license plate, but with dots and lines. Practical tests have shown that the continuous wave is only clean and constant if it is ensured that there is no decrease in energy during the transition from one character to the other. Complicated relay arrangements have already been proposed to solve this problem, which are intended to ensure that the activation of one reflector coincides precisely with the deactivation of the other reflector. The resulting key arrangements are extremely complicated and, above all, they must be meticulously maintained so that the error that is to be eliminated does not recur after prolonged operation. It must also be taken into account that the second reflector becoming effective too early also makes the continuous wave ineffective. It is easy to see that the task here is by no means so easily accomplished in this way.
Vorliegende Erfindung schlägt vor, die Strahlungsdiagramme so zu wählen, daß der Schnittpunkt der durch die Tastung der Reflektoren entstehenden Strahlungscharakteristik auf der Charakteristik der Erregerantenne liegt, die entsteht, wenn die Reflektoren unwirksam sind. In der beiliegenden Abbildung ist die Erregerantenne, die dauernd vom Hochfrequenzsender gespeist wird, mit E bezeichnet, die beiden Reflektoren mit 12i und 12z. Die Schaltanordnung ist nicht weiter veranschaulicht, da dieselbe mit der des Hauptpatents identisch ist. Die beiden durch Tastung der Reflektoren entstehenden Strahlungscharakteristiken sind mit b und c bezeichnet. a ist die Strahlungscharakteristik, die der Erregerantenne allein entspricht, d. h. die dann auftritt, wenn beide Reflektoren unwirksam sind. Erfindungsgemäß liegt der Schnittpunkt P von b und c auf dem Kreis a. Würde :er auf P1 liegen, wie es der Abb. z des Hauptpatents entspricht, so ergibt sich folgendes: Geht im Punkt P1 b in c über ohne Zeitdifferenz zwischen den einzelnen Zeichen, so ist der Dauerstrich sauber. Dies ist der Fall, der, wie oben erwähnt, durch komplizierte Relaisanordnungen erreicht werden soll. Erfolgt aber das Wirksamwerden später als das Unwirksamwer den, so tritt während der Zeitdifferenz am Empfangsort ein Anwachsen der Lautstärke von PI nach P auf, da während der Umschlagszeit der Erregerdipol allein strahlt, d. h. die Feldstärke entsprechend der Strahlungscharakteristika (Kreis) vorhanden ist; d. h. dem Dauerstrich überlagert sich eine leichte Modulation entsprechend diesem Energieanwachsen. Erfolgt die Umschaltung zu früh, d. h. sind einen Augenblick lang beide Reflektoren wirksam, dann erfolgt ein Anwachsen von P1 nach P= hin, da beide Reflektoren -wirksam sind (vgl. Strahlungscharakteristikd des Hauptpatents).The present invention proposes that the radiation diagrams be selected so that the intersection of the radiation pattern resulting from the touching of the reflectors lies on the characteristic of the exciter antenna which arises when the reflectors are ineffective. In the accompanying illustration, the exciter antenna, which is continuously fed by the high-frequency transmitter, is designated with E, the two reflectors with 12i and 12z. The switching arrangement is not further illustrated since it is identical to that of the main patent. The two radiation characteristics produced by touching the reflectors are denoted by b and c. a is the radiation pattern that corresponds to the exciter antenna alone, ie that occurs when both reflectors are ineffective. According to the invention, the intersection point P of b and c lies on the circle a. If: it were on P1, as it corresponds to Fig. Z of the main patent, the following results: If at point P1 b goes over into c without a time difference between the individual characters, the continuous line is clean. This is the case, which, as mentioned above, is intended to be achieved by complicated relay arrangements. However, if it becomes effective later than ineffective, the volume increases from PI to P during the time difference at the receiving location, since the exciter dipole alone radiates during the transition period, ie the field strength is present according to the radiation characteristics (circle); ie a slight modulation corresponding to this increase in energy is superimposed on the continuous wave. If the switchover takes place too early, ie if both reflectors are active for a moment, then there is an increase from P1 to P =, since both reflectors are active (see radiation characteristics of the main patent).
Werden erfindungsgemäß die Strahlungscharakteristiken so eingerichtet, daß der Punkt P von b und c auf a liegt, so kann der geschilderte Mangel nicht auftreten. Erfolgt die Tastung mit Zeitverzögerung, - so wird während der Zeichenpause entsprechend det Kreischarakteristik a gestrahlt; die Amplitude nimmt aber nicht zu, wie sich ohne weiteres aus der Abbildung ersehen läßt. Man braucht also nur dafür zu sorgen, daß mit Zeitverzögerung getastet wird, d. h. keinen Augenblick beide Reflektoren eingeschaltet sind, eine Forderung, die sich ohne weiteres erfüllen läßt" durch die Anwendung eines einfachen Kollektors; denn die Relais sorgen ganz allein dafür, daß eine gewisse geringe Zeitverzögerung vorhanden ist.If, according to the invention, the radiation characteristics are set up in such a way that the point P of b and c lies on a , the deficiency described cannot occur. If the keying takes place with a time delay, radiation is carried out during the pause according to the circle characteristic a; however, the amplitude does not increase, as can be readily seen from the figure. You only need to ensure that keying takes place with a time delay, that is to say that both reflectors are not switched on for a moment, a requirement that can easily be met "by using a simple collector; because the relays alone ensure that a certain there is a slight time delay.
