Description
Anordnung zur Bestimmung der Richtung von Schallwellen Zur Bestimmung der Richtung von Schallwellen, insbesondere unter Wasser, bedient man sich häufig der Interferenzmethode. Bei dieser Methode «-erden die von den Empfängern erzeugten Ströme durch Verzögerungsmittel in Phase gebracht und einander überlagert. Je nachdem, ob die Ströme die gleiche oder entgegengesetzte Phase aufweisen, erhält man an dem Anzeigeinstrument oder im Abhörtelephon ein Minimum oder Maximum (Minimum- oder Maximummethode). Sowohl die Minimum- als auch die Maximummethode weisen verschiedene - Nachteile auf.Arrangement for determining the direction of sound waves For determination the direction of sound waves, especially under water, is often used the interference method. With this method "-grounds the generated by the receivers Currents brought into phase and superimposed on each other by delay means. Depending on, whether the currents are in the same or opposite phase is indicated by the Display instrument or in the wiretapping telephone a minimum or maximum (minimum or Maximized method). Both the minimum and maximum methods have different ones - Disadvantages.
Man kann diese Nachteile beseitigen, wenn man gemäß der Erfindung beide Methoden gleichzeitig anwendet. Es empfiehlt sich dabei, die Einrichtung derart zu treffen, daß das Ergebnis der Maximummethode an einem Meßinstrument angezeigt wird, während man die Richtung nach der Minimummethode durch Abhören feststellt.One can eliminate these disadvantages if one according to the invention uses both methods at the same time. It is advisable to set up the device in this way to ensure that the result of the maximum method is displayed on a measuring instrument while the direction is determined by eavesdropping using the minimized method.
In der Abbildung ist eine Schaltung zur Ausführung des Verfahrens gemäß der Erfindung dargestellt. Mit i und -, sind zwei Empfänger bezeichnet. Die von den Empfängern erzeugten Ströme werden über die Verzögerungsleitungen 3 und 4 den Primärwicklungen 5 und 6 der Transformatoren 7 und 8 zugeführt. An Stelle zweier Empfänger kann natürlich auch eine beliebig größere Anzahl von Empfängern oder Empfängergruppen treten. Die Transformatoren 7 und 8 sind mit zwei Sekundärwicklungen 9, io und i i, 12 ausgerüstet. Die Sekundärwicklungen 9 und i i sind gegeneinandergeschaltet und über den Verstärker 13 an das Telephon 14 angeschlossen. Die Wicklungen io und i2 sind in der gleichen Richtung hintereinandergeschaltet und wirken über den Verstärker 15 und den Gleichrichter 16 auf das Meßinstrument i7. Bei Phasengleichheit der den Empfängern 5 und 6 zugeführten Ströme schweigt das Telephon 14, dagegen zeigt das Meßinstrument 17 einen verhältnismäßig kräftigen Ausschlag.The figure shows a circuit for carrying out the method according to the invention. With i and -, two receivers are designated. The currents generated by the receivers are fed to the primary windings 5 and 6 of the transformers 7 and 8 via the delay lines 3 and 4. Instead of two recipients, any number of recipients or groups of recipients can of course be used. The transformers 7 and 8 are equipped with two secondary windings 9, io and ii, 12. The secondary windings 9 and ii are connected to one another and connected to the telephone 14 via the amplifier 13. The windings io and i2 are connected in series in the same direction and act on the measuring instrument i7 via the amplifier 15 and the rectifier 16. If the currents fed to the receivers 5 and 6 are in phase, the telephone 14 is silent, but the measuring instrument 17 shows a relatively strong deflection.
Unter Umständen kann es zweckmäßig sein, das Telephon 14 mit dem Meßinstrument 17 einschließlich Gleichrichter 16 zu vertauschen. Dies kann in einfachster Weise durch Vertauschen der Zuleitungen zu einer der Primärwicklungen 5 oder 6 geschehen. Bei der in der Abbildung dargestellten Schaltung liegt in der Zuleitung zur Wicklung 5 der Polwender 18.Under certain circumstances it can be useful to swap the telephone 14 with the measuring instrument 17 including the rectifier 16. This can be done in the simplest way by swapping the leads to one of the primary windings 5 or 6. In the circuit shown in the figure, the pole inverter 18 is located in the supply line to the winding 5.
