Description
Die Phasenmodulation einer Impulsreihe erfolgt bisher beispielsweise dadurch, daß zunächst eine amplitudenmodulierte äquidistante Impulsfolge 'erzeugt wird und daß anschließend in einer Röhrenschaltung jeder einzelne Impuls über eine lineare Sägezahnspannung zeitlich um einen Betrag verschoben wird, der seiner Amplitude proportional ist. Eine weitere Möglichkeit zur Erzeugung von phasenmodulierten Impulsen besteht in der Verwendung eines Kathodenstrahlschalters, wobei man die den Impulsen aufzudrückende Modulation der Umlaufgeschwindigkeit des Elektronenstrahles überlagert.The phase modulation of a series of pulses has hitherto been done, for example in that initially an amplitude-modulated equidistant pulse sequence is generated and that then each individual pulse in a tube circuit via a linear sawtooth voltage is shifted in time by an amount that corresponds to its amplitude is proportional. Another way to generate phase-modulated pulses consists in using a cathode ray switch, taking the pulses Overlaid modulation of the rotational speed of the electron beam.
Der Erfindung liegt ebenfalls die Aufgabe zugrunde, phasenmodulierte Impulse zu erzeugen. Sie geht von einer bekannten Anordnung aus, bei der einem Laufzeitorgan die zu modulierende Impulsreihe zugeführt wird, während die elektrischen Eigenschaften des Laufzeitorgans von der Modulationsspannung beeinflußt werden. Gemäß der Erfindung soll das Laufzeitorgan als Laufzeitkette ausgebildet werden, deren Laufzeit durch Beeinflussung der Dielektrizitätskonstanten in Abhängigkeit von der Modulationsspannung verändert wird. Eine solche Laufzeitkette kann beispielsweise aus einer Spule bestehen, die auf einem Keramikhohlzylinder aufgewickelt ist. Die Beeinflussung der Dielektrizitätskonstante erfolgt in der Weise, daß man an den Stirnseiten des Keramikzylinders Kapazitätsplatten anordnet und an diese Platten die Modulationsspannung anlegt. Die in der Phase in Abhängigkeit von der Modulationsspannung zu modulierenden Impulse werden über die auf dem Keramikzylinder angeordnete Spule geschickt.The invention is also based on the object of phase-modulated To generate impulses. It is based on a known arrangement in which a runtime organ the pulse train to be modulated is supplied, while the electrical properties of the runtime organ can be influenced by the modulation voltage. According to the invention the runtime organ is to be designed as a runtime chain, the runtime of which is through Influence of the dielectric constant as a function of the modulation voltage is changed. Such a delay chain can consist of a coil, for example, which is wound on a ceramic hollow cylinder. Influencing the dielectric constant takes place in such a way that capacity plates are attached to the end faces of the ceramic cylinder and applies the modulation voltage to these plates. The in phase in Depending on the modulation voltage to be modulated pulses are about the sent on the ceramic cylinder arranged coil.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt. Auf einem Keramikhohlzylinder i, dessenInnenbohrung mit einer metallisch leitenden Schicht versehen ist, befindet sich in bekannter Weise eine Spule 2, die mit dem Innenbelag zusammen eine unsymmetrisch ausgeführte Laufzeitspule bildet. An den Stirnseiten dieses Zylinders sind zwei plattenförmige Elektroden 4 und 5 angeordnet, die beispielsweise aus einer Titan-Oxyd-Verbindung bestehen. Legt man an diese Platten die Modulationsspannung an, so werden die den Anschlüssen 3 der Laufzeitspule zugeführten Impulse in ihrer Phase entsprechend der angelegten Modulationsspannung verschoben. An Stelle der Verwendung eines Keramikhohlzylinders, dessen Dielektrizitätskonstante in Abhängigkeit der Modulationsspannung verändert wird, kann es mitunter von Vorteil sein; die Laufzeitkette aus einer auf einem Kern von Keramik-und Eisenteilchen angeordneten Spule zu bilden. Man muß dann Mittel vorsehen, die sowohl die Dielektrizitätskonstante als auch die Permeabilität dieses Kernes in Abhängigkeit von der Modulationsspannung verändern. Mit einer solchen Ausführungsform erreicht man, daß der Wellenwiderstand stets einen konstanten Wert behält und daß sich nur die Laufzeit y L - C ändert. Der Vorteil einer solchen Anordnung liegt darin, daß die Laufzeitkette auch während der Modulation reflexionsfrei abgeschlossen bleibt.An embodiment of the invention is shown in the figure. On a ceramic hollow cylinder i, the inner bore of which is provided with a metallically conductive layer, there is a coil 2 in a known manner, which together with the inner lining forms an asymmetrically designed run-time coil. Two plate-shaped electrodes 4 and 5, which for example consist of a titanium-oxide compound, are arranged on the end faces of this cylinder. If the modulation voltage is applied to these plates, the pulses fed to the connections 3 of the delay coil are shifted in their phase in accordance with the applied modulation voltage. Instead of using a ceramic hollow cylinder, the dielectric constant of which is changed as a function of the modulation voltage, it can sometimes be advantageous; to form the transit time chain from a coil arranged on a core of ceramic and iron particles. Means must then be provided which change both the dielectric constant and the permeability of this core as a function of the modulation voltage. With such an embodiment it is achieved that the wave resistance always maintains a constant value and that only the running time y L - C changes. The advantage of such an arrangement is that the delay chain remains reflection-free even during the modulation.
