Description

Die Erfindung bezieht sich auf eine Einrichtung zur stetig veränderbaren Phasenverschiebung von Hochfrequenzimpulsen, wie sie für die Zwecke der Funkmeßtechnik zur Regelung von künstlichen Echos auf beliebige Zielentfernungen benötigt wird, und zwar ist gemäß der Erfindung bei einer derartigen Einrichtung zwischen dem Impulsfolgefrequenzgenerator und dem Impulserzeugungsgerät ein regelbarer Phasenschieber vorgesehen. Durch eine derartige Anordnung ergibt sich eine wesentliche Vereinfachung gegenüber den bekannten Einrichtungen, bei denen die stetig veränderbare Phasenverschiebung des Hochfrequenzimpulses bzw. die Regelarbeit des künstlichen Echos auf beliebige Zielentfernung im Hochfrequenzteil bewirkt wird, denn wenn die Phasenverschiebung zwischen dem Hochfrequenzsender und der Antenne erzeugt wird, erfordert dies für jede Sendefrequenz eine neue Abstimmung des Phasenschiebers, und außerdem muß der Phasenschieber als verhältnismäßig komplizierte Lecherleitung ausgebildet werden. The invention relates to a device for continuously variable Phase shift of high-frequency pulses, as they are for the purposes of radio measurement technology is required to control artificial echoes at any target distance, namely is according to the invention in such a device between the pulse repetition frequency generator and a controllable phase shifter is provided to the pulse generator. By a such an arrangement results in a substantial simplification compared to the known Facilities in which the continuously variable phase shift of the high-frequency pulse or the control work of the artificial echo at any target distance in the high-frequency part is caused because if the phase shift between the high frequency transmitter and the antenna is generated, this requires a new tuning for each transmission frequency of the phase shifter, and also the phase shifter must be relatively complicated Lecher line be trained.

In Fig. I ist das Schaltbild eines Ausführungsbeispieles nach der Erfindung dargestellt. G ist der Impulsfolgefrequenzgenerator und S der impulsmodulierte Hauptsender. Zwischen dem Generator G und dem Impulserzeugungsgerät IG ist der regelbare Phasenschieber Ph angeordnet. HS ist ein Hilfssender, dessen Abstimmfrequenz gleich der des Hauptsenders ist, E der Empfänger und Si das Sichtgerät, vorzugsweise eine Braunsche Röhre. Auf dem Bildschirm der Braunschen Röhre erscheinen über einer in Kilometer geeichten horizontalen Skala die Impulse als zackenförmige Auslenkungen. 51 ist der Sendeimpuls und KE das künstliche Echo, das in seiner Zielentfernung durch Verstellen des Phasenschiebers Ph stetig regelbar ist. Der veränderbare Phasenschieber Ph läßt sich, wie das Ausführungsbeispiel für eine Impulsfolgefrequenz von I500 Hz in Fig. 2 zeigt, sehr einfach gestalten. A ist dabei der Eingang und B der Ausgang. In Fig. I is the circuit diagram of an embodiment according to Invention shown. G is the pulse repetition frequency generator and S is the pulse modulated one Main broadcaster. The controllable one is between the generator G and the pulse generator IG Phase shifter Ph arranged. HS is an auxiliary transmitter whose tuning frequency is the same that of the main transmitter, E the receiver and Si the display device, preferably one Braun tube. On the screen of the Braun tube appear above an in Kilometers calibrated horizontal scale the impulses as jagged deflections. 51 is the transmission pulse and KE is the artificial echo that is in its target distance is continuously adjustable by adjusting the phase shifter Ph. The changeable phase shifter Ph can be, like the embodiment example, for a pulse repetition rate of I500 Hz in Fig. 2 shows, make it very simple. A is the input and B is the output.

Der Querkondensator C2 erzeugt eine solche Voreilung der Impulsfolgefrequenzspannung, daß der künstliche Impuls sicher bis zur Zielentfernung Null eingestellt werden kann. Mit dem veränderlichen Längskondensator C1, der durch den Widerstand W überbrückt ist, läßt sich eine beliebig einstellbare Nacheilung erzeugen, die einer stetig veränderbaren Zielentfernung des künstlichen Echos entspricht. Der veränderliche Kondensator C1 läßt sich auf beliebige Zielentfernungen des künstlichen Echos eichen.The shunt capacitor C2 generates such a lead of the pulse repetition frequency voltage, that the artificial impulse can be set safely up to the target range zero can. With the variable series capacitor C1, which is bridged by the resistor W. is, an arbitrarily adjustable lag can be generated, one of which is continuous variable target distance of the artificial echo corresponds. The changeable one Capacitor C1 can be calibrated to any target distance of the artificial echo.

Die Amplitude des Hochfrequenzimpulses bzw des künstlichen Echos ist bei der Einrichtung nach der Erfindung unabhängig von der eingestellten Phasenlage bzw. von der Zielentfernung, sofern das Impulsgerät so ausgebildet wird, daß die Impulsfolgefrequenzspannung nur zum Anstoßen des eigentlichen Impulses verwendet wird. Eine konstante Amplitude des Hochfrequenzimpulses ist aber bekanntlich für Meßzwecke von besonderer Bedeutung. The amplitude of the high frequency pulse or the artificial echo is independent of the set phase position in the device according to the invention or from the target range, provided the pulse device is designed so that the Pulse repetition voltage only used to initiate the actual pulse will. However, a constant amplitude of the high-frequency pulse is known for Measurement purposes of particular importance.
