Description

Bei Verfahren zur Ortsbestimmung mittels drahtloser Wellen werden Impulse sehr kurzer Dauer hsnötigt. Man kann derartige Impulse durch entsprechende tastung drahtloser Sender erzeugen und die Leistung der Sender entsprechend., der maximalen Amplitude des Impulses bemessen, Der Sender wird dann nur während der kurzen Impulsdauer in seiner Leistung ausgenutzt. Da derartige Anlagen in vielen Fällen jedoch mit möglichst geringem Materialaufwand und Leistungsbedarf arbeiten sollen, besteht die forderung, die Anlage so auszugestalten, daß mit derartigen Leistungsüberschüssen, wie sie beim erwähnten Verfahren notwendig sind, nicht gearbeitet zu werdan braucht. Man kann sich hierzu die erwähnte Tatsache zunutze machen, daß die Impulse nur von sehr kurzer Dauer sind. Man kann den Sender kurzzeitig sehr stark überlasten, dme daß dieser, insbesondere seine Röhren, beschädigt werden. da auf den kurzzeitigen Impuls eine größere Pause folgt. Die Erfindung befaßt sich mit einer Schaltungsanordnung zur impulsmäßigen Überlastung von Senderöhren, welche dadurch gekennzeichnet ist, daß zur Erzeugung von dm-wellen in selbsterregter Rückkopplungsschaltung eine Ultrakurzwellenröhre mit radial angeordneten. die Elektroden frei tragenden Zuführungen (eichelrühre) derart verwendet ist, daß ihre sehr hohe anodenspannung über eine Taströhre zugeführt wird. die nur für die Zeitdauer der auszusendenden Impulse geöffnet ist. In the case of methods for determining the location by means of wireless waves Very short pulses required. One can get such impulses through appropriate Generate keying of wireless transmitters and the output of the transmitter accordingly., the The maximum amplitude of the pulse is measured, the transmitter is then only during the short pulse duration exploited in its performance. Since such systems in many In cases, however, work with the least possible material and power requirements should, there is a requirement to design the system so that with such Performance surpluses, as they are necessary with the mentioned procedure, not worked to be needed. One can make use of the mentioned fact that the impulses are very short-lived. You can use the station very briefly heavily overload, that is, that this, in particular its tubes, are damaged. because the brief impulse is followed by a longer pause. The invention is concerned with a circuit arrangement for pulsed overloading of transmission tubes, which characterized in that for generating dm waves in a self-excited feedback circuit an ultra-short wave tube with radially arranged. the electrodes are self-supporting Feeds (glans) are used in such a way that their very high anode voltage is supplied via a feeler tube. which are only for the period of time to be sent out Impulse is open.

In der Abbildung ist eine Anordnung zur Eutfernungsmessung nach der Impulsmethode gezeigt, um gleich ein Anwendungsbeispiel des Erfindungsgedankens zu veranschaulichen. The illustration shows an arrangement for distance measurement after the Impulse method shown to the same an application example of the inventive concept to illustrate.

Die Aniage besteht aus einem Kippgenerator K, der im wesentlichen aus einem gasgefüllten rohr mit Gittersteuerung, Ladekondensator C und Ladewiderstand R6 besteht.The system consists of a relaxation generator K, which is essentially from a gas-filled tube with grid control, charging capacitor C and charging resistor R6 exists.

Es handelt sich hier um die bekannte Schaltung zur Erzeugung einer sägezahnartigen Spannungskurve. An den Kippgenerator ist ein Zeitkreis angeschlossen, der aus einem Kondensator C1 und einem Widerstand H' besteht. Durch diesen Zeitkreis wird die Sägezahn spannung derart differenziert. daß Spannungsspitzen entstehen. In der Abb. 2 a ist der Spannungsverlauf am Kondensator C und in der Abb. 2b der am Widerstand W gezeigt, Die entstehenden Spannungsspitzen liegen am Gitter der Röhre R1. An R1 ist mit Hilfe eines Kondensators und Widerständen ein Verstärkerrohr R2 angekoppelt. Durch das Rohr R. wird der eigentliche Dezimetersender getastet. Der Dezimetersender besteht aus einem Eichelrohr S an sich bekannter Art, zwischen dessen Gitter und Anode in an sich bekannter ÄVeise der Schwingungskreis liegt.This is the well-known circuit for generating a sawtooth-like voltage curve. A timing circuit is connected to the tilt generator, which consists of a capacitor C1 and a resistor H '. Through this time cycle the sawtooth voltage is differentiated in this way. that voltage peaks arise. In Fig. 2a the voltage curve across the capacitor C and in Fig. 2b is the shown at the resistor W, the resulting voltage peaks are on the grid of the Tube R1. An amplifier tube is connected to R1 with the help of a capacitor and resistors R2 coupled. The actual decimeter transmitter is keyed through the tube R. The decimeter transmitter consists of an acorn tube S of a type known per se, between the grid and anode of which the oscillation circuit lies in a manner known per se.

Alit dem Schwingungskreis ist induktiv ein Dipol zur Ausstrahlung der rezeugten Schwingungen gekoppelt. Gitter und Kathode sind durch eine Dezimeterwellendrossel verbunden.With the oscillation circuit there is inductively a dipole for radiation coupled to the generated vibrations. The grid and cathode are through a decimeter wave choke tied together.

Die Kathode ist über eine Drossel D1 mit der Anode des Rohres R2 und die Anode über eine Drossel D2 mit dem unteren Ende des Anodenwiderstandes Ra (positiver Punkt der Spannungsquelle) verbunden. Die Anodenspannung wird der für die Anordnung gemeinsamen Spannungsquelle entnommen. Der Arbeitspunkt des Rohres R2 ist so eingestellt. daß das mit thm in Serie liegende Senderohr S beim Nichtarbeiten des Impulsgenerators nicht schwingt. Sobald Impulse auftreten, wird das Rohr 22 geöffnet und der Sender für die Dauer der Impulse hochgetastet. Mit dem bekannten Eichelrohr der type S D1, das normalerweise im Dauerstrich nur eine Leistung von 0,1 Watt abgeben kann, konnten Leistunggen bis zu etwa 70 Watt erzielt werden.The cathode is connected to the anode of the tube R2 and via a choke D1 the anode via a choke D2 with the lower end of the anode resistance Ra (more positive Point of the voltage source). The anode voltage becomes that for the arrangement common voltage source. The working point of the pipe R2 is set in this way. that the transmission tube S lying in series with thm when the pulse generator is not working does not vibrate. As soon as pulses appear, the tube 22 is opened and the transmitter keyed up for the duration of the impulses. With the well-known glans tube of the type S D1, which can normally only deliver a power of 0.1 watt in a continuous wave, Power levels of up to about 70 watts could be achieved.

Die dargestellte Schaltung kann dahin ergänzt werden, daß ber Kippgenerator K selbst fremdgesteluert wird, z. B. in der Weise, daß der ausgesandte Impuls auf einen Empfünger gelangt und durch diesen den Kippgenerator auslöst. Die so entstehende Impulsfrequenz ist dann ein NIaß für die Entfernung. The circuit shown can be supplemented to include a relaxation generator K itself is externally controlled, e.g. B. in such a way that the transmitted pulse on reaches a receiver and triggers the tilt generator through it. The resulting Pulse frequency is then a measure of the distance.
