Im folgenden wird ein Ausführungsbeispiel einer Anordnung zur Durchführung des erfindungsgemäßen Verfahrens anhand der Zeichnung nähjr beschrieben.The following is an embodiment of an arrangement for carrying out the method according to the invention described in detail with reference to the drawing.
Die Figur zeigt Anschlüsse 13 bis 15 für die O—W, N-S- und die Hilfsantennenspannung. In einem Summierglied 6 wird die Summe der N—S- und der O— W-Spannung gebildet. Die erwähnten vier Spannungen können über eine Schalteinrichtung 2 mit drei Doppelschaltcrn 3 bis 5 den Eingängen eines Zwcikanalempfängcrs 1 zugeführt werden. Am Ausgang des Zweikanalempfängers ist eine weitere Schalteinrichtung 2' mit ebenfalls drei Doppelschaltern 3' bis 5' vorgesehen.The figure shows connections 13 to 15 for the OW, LV and the auxiliary antenna voltage. In a summing element 6, the sum of the N — S and the O — W voltages is formed. The four voltages mentioned can be fed to the inputs of a dual-channel receiver 1 via a switching device 2 with three double switches 3 to 5. At the output of the two-channel receiver, a further switching device 2 'is provided, likewise with three double switches 3' to 5 '.
In einer sich zyklisch wiederholenden Schaltfolge mit drei Schaltschritten werden zunächst die Doppelschalter 3 und 3' geschlossen. An beiden Eingängen des Zwei-In a cyclically repeating switching sequence with three switching steps, the double switches 3 and 3 'are initially closed. At both entrances of the two
bo kanalempfängers liegt dann der Ausgang des Summiergliedes 6, so daß beide Eingänge mit der Summe der Peilspannungen beaufschlagt sind. Gleichzeitig sind die Anschläge des Zweikanalcmpfängers mit einem Abglcichdctcktor 8 verbunden, der seinerseits über bcson-bo channel receiver is then the output of the summing element 6, so that the sum of the bearing voltages is applied to both inputs. At the same time they are The two-channel receiver stops with a comparison gate 8 connected, in turn via bcson-

Im nächsten Schaltzustand sind in jedem Zyklus die Doppelschalter 4 und 4' durchgeschaltet, wobei demIn the next switching state, the double switches 4 and 4 'are switched through in each cycle, with the
Kanal 1 die Hilfsantennenspannung und dem Kanal 2 die Summe der Peilspannungen zugeführt wird. Die Ausgänge des Zweikanalempfängers sind an einen Phasendetektor 9 angeschlossen. Die in diesem Phasendetektor bestimmte Phasendifferenz zwischen der Referenzphase der Hilfsantennenspannunp und der Phase der Peilspannungen wird in einem Analogspeicher 10 gespeichert Der Speicher steuert die Einstellung eines verstellbaren Phasendrehgliedes 11.Channel 1 is supplied with the auxiliary antenna voltage and channel 2 is supplied with the sum of the DF voltages. the Outputs of the two-channel receiver are connected to a phase detector 9. The ones in this phase detector certain phase difference between the reference phase of the auxiliary antenna voltage and the phase the bearing voltages is stored in an analog memory 10. The memory controls the setting of a adjustable phase rotating member 11.
Im dritten Schaltzustand sind die Doppelschalter 5 und 5' geschlossen. Am Kanal 1 liegt dann die N-S-, am Kanal 2 die O— JV-Peilspannung an. Der Ausgang des Kanals 1 ist auf die Vertikalablenkplatten, der Ausgang des Kanals 2 auf die Horizontalablenkplatten einer Anzeigeröhre 12 durchgeschaltet Zugleich wird in einem Summierglied 7 am Ausgang des Zweikanalempfängers die Summe der verstärkten und gegebenenfalls in der Frequenz herabtransponierten Peilspannungen gebildet und nach einer Phasenverschiebung ΔΨ im Phasendrehglied 11, die der gespeicherten Phasendiherenz zwisehen der Referenzphase und der Phase der Peilspannungen entspricht, einer der Helligkeitssteuerung dienenden Elektrode der Anzeigeröhre 12 zugeführtIn the third switching state, the double switches 5 and 5 'are closed. At channel 1 the NS-, at channel 2 the OJV-DF voltage is applied. The output of channel 1 is on the vertical deflection plates, the output of the channel 2 to the Horizontalablenkplatten a display tube 12 connected through the same time is formed in a summing element 7 at the output of the two-channel receiver, the sum of the amplified and optionally herabtransponierten in the frequency Peilspannungen and after a phase shift ΔΨ in Phase rotation element 11, which corresponds to the stored phase diherence between the reference phase and the phase of the bearing voltages, is supplied to an electrode of the display tube 12 which is used for brightness control
Es ist noch darauf hinzuweisen, daß die Summierglieder 6 und 7 die beiden Eingangsspannungen erst um 90° in der Phase gegeneinander drehen und sie dann zusammenstellen. Die entstehende Vektorsumme gibt eine Ausgangsspannung mit konstanter Amplitude aber mit veränderlicher Phase, die mit dem zu peilendem Ziele zusammen rotiert Im Unterschied hierzu wird die Ausgangsspannung der Hilfsantenne, unabhängig von dvm Azimutwinkel des Zieles, immer um 90° gegen die N— S- oder O— VV-Spannung verschoben, so daß sie als feste Phasenreferenz dienen kann.It should also be pointed out that the summing elements 6 and 7 first rotate the two input voltages through 90 ° in phase with one another and then put them together. The resulting vector sum gives an output voltage with constant amplitude but with variable phase, which rotates together with the target to be tracked.In contrast to this, the output voltage of the auxiliary antenna, regardless of the azimuth angle of the target, is always 90 ° against the N, S or O - VV voltage shifted so that it can serve as a fixed phase reference.
