Funkpeileinrichtung zur optischen Anzeige eines Peilminimums oder -maximums Zusatz zum Patent 700 26 Das Hauptpatent 700 262 betrifft eine Funkpeileinrichtung zur optischen Anzeige eines Peilminimums oder -maximums. Das Wesen der Einrichtung nach dem Hauptpatent besteht dann, daß Mittel vorgesehen sind, um eine die jeweilige Stellung der rotierenden Empfangsantenne bzw. des richtungsempfindlichen Empfangs organs kennzeichnende elektrische Größe zu erzeugen und daß weiterhin Mittel vorgesehen sind, um den Kathodenstrahl einer Braunschen Röhre einerseits in Abhängigkeit von dieser elektrischen Größe und andererseits in Abhiingigkeit vo;n der vom drehbaren richtungsempfindlichen Empfangs Organ aufgenomm en,en Energie abzulenken.Radio direction finder for the optical display of a bearing minimum or -maximum addition to patent 700 26 The main patent 700 262 relates to a radio direction finder for optical display of a bearing minimum or maximum. The essence of the facility according to the main patent, there is then that means are provided to one the respective Position of the rotating receiving antenna or the direction-sensitive reception organs to generate characteristic electrical quantity and that further means are provided are to the cathode ray of a Braun tube depending on the one hand this electrical quantity and, on the other hand, depending on that of the rotatable direction-sensitive receiving organ to divert energy. Im Hauptpatent wurde weiterhin bereits vorgeschlagen, der oszillographisch dargestellten Peilkurve beim Durchlaufen des richtungsempfindlichen Organs durch bestimmte. In the main patent it was also suggested that the oscillographic bearing curve shown when passing through the direction-sensitive organ certain. Winkelstellungen zusätzliche Sichtmerkmale zur Kennzeichnung dieser Winkelstellungen zu überlagern, um in Verbindung mit einer festen skalaren Teilung der Anzeigefläche die Ablesung der Peilung nach Gradbruchteilen zu ermöglichen.Angular positions additional visual features to identify them To superimpose angular positions in connection with a fixed scalar division the display area to enable the bearing to be read by fractions of a degree. Die Erfindung betrifft eine Weiterbildung dieses Vorschlages des Hauptpatents und besteht darin, daß der Oszillographenstrahl eine der Peilkurve überlagerte vollständige Skala auf den Leuchtschirm aufzeichnet. Vorteilhaft können dazu auch Mehrstrahloszillographen Verwendung finden. The invention relates to a further development of this proposal Main patent and consists in the fact that the oscilloscope beam is one of the bearing curve superimposed full scale is recorded on the luminescent screen. Can be beneficial multi-beam oscillographs are also used for this purpose. Der Ersatz einer festen Skala durch eine vom Kathodenstrahl elektrisch geschriebene Skala bietet insofern einen wesentlichen Vorteil, als eine auf dem Leuchtschirm fest angebrachte Skalenteilung die Verwendung ein er Zeitablenkspannung erfordert die in bezug auf Anfangs- und Endamplituden und Linearität höchste Anforderungen erfüllen muß. The replacement of a fixed scale by one from the cathode ray electric The written scale offers a significant advantage in that it is based on the Luminous screen permanently attached graduations the use of a time deflection voltage requires the highest standards in terms of start and end amplitudes and linearity must meet. Jede Abweichung von der vorgegebenen Anfangs- und Endamplitude und der Linearität würde bewirken, daß bei einer bestimmten Winkelstellung des Peilorgans der Kathodenstrahl nicht über dem zugeordneten Sollwert der festen Skala, sondern rechts o.der links davon steht, und daß die Peilung infolgedessen mit einem entsprechenden Peilfehier behaftet ist.Any deviation from the specified start and end amplitude and the linearity would have the effect that at a certain angular position of the bearing organ the cathode ray does not exceed the assigned target value on the fixed scale, but rather to the right or the left of it, and that the bearing is consequently marked with a corresponding Peilfehier is afflicted. Wird dagegen die Skala auf elektrischem Wege gezeichnet, so können Amplituden- und Linearitätsschwankungen der Zeitablenkspannung nur noch bewirken, daß sich die Lage der Skalenstriche etwas verschiebt; die räumliche Zuordnung der Peilkurve zu den Skalenstrichen kann sich jedoch nicht verändern. If, on the other hand, the scale is drawn electrically, then Amplitude and linearity fluctuations of the time deflection voltage only cause that the position of the scale lines shifts somewhat; the spatial allocation of the However, the bearing curve to the scale lines cannot change.
