Description
Die Erfindung betrifft eine Einrichtung zur gleichzeitigen Anzeige sowohl des Abstandes als auch der Richtung mehrerer reflektierender Gegenstände, die sich im Strahlnngsfeld eines nach der Impulsmethode arbeitenden, aus Sender und Empfänger bestehenden Rückstrahlgerätes befinden. The invention relates to a device for simultaneous display both the distance and the direction of several reflective objects, which are in the radiation field of a transmitter working according to the impulse method and receiver of the existing reflex device.
Es. sind Rüchstrahlgeräte bekannt, die entweder eine Richtungsbestimmung nach dem Feldstärkevergleichsprinzip durchführen oder aber die Durchführung einer Entfernuugsmessuug nach der Rückstrablmetholde ermöglichen. Es. ist auch bereits eine Anordnung bekannt, die es ermöglicht, sowohl die Richtung als auch den Abstand eines reflektierenden. Gegenstandes zu ermitteln. Bei dieser bekanten Anosrdn,un,g wird mit Schallwellen gearbeitet. Die Richtung der reflektierten Schallwellen wird mit Hilfe einer spiegelähnlichen Einrichtung, die um eine vertikale Achse schwenkbar ist, ermittelt, wobei deren jeweilige Stellung an einem Kompaß abgelesen werden kann. Die Entfernung wird nach der bekannten Laufzeitmethode durch Messung des Hin- und Rückweges der ausgesandten Schallwellen ermittelt. It. Rüchstrahlgeräte are known that either determine the direction carry out according to the field strength comparison principle or carry out a Allow distance measurement after the return method. It. is also already an arrangement is known that allows both the direction and the distance one reflective. To determine the object. With this known anosrdn, un, g is worked with sound waves. The direction of the reflected sound waves will be with the help of a mirror-like device that can be pivoted about a vertical axis is determined, their respective positions being read off on a compass can. The distance is determined according to the known transit time method by measuring the forward and the return path of the emitted sound waves is determined.
Mit dieser bekannten Einrichtung ist es jedoch nur möglich, gleidizeitig die Entfernung und Richtung eines einzigen reflektierenden Gegenstandes festzustellen. With this known device, however, it is only possible simultaneously determine the distance and direction of a single reflective object.
Zur Lösung der der Erfindung zugrunde liegenden Aufgabe, gleichzeitig den Abstand und die Richtung von mehreren reflektierenden. Gegenständen anzuzeigen, wird gemäß der Erfindung vorgeschlagen, das Rückstrahlgerät mit einem Richtantennensystem zu versehen, das. eine periolische Schwenkbewegung a,usführt. Der Elektronenstralil des als Anzeigeorgan vorgesehenen Braunschen Rohres wird dann einerseits in Abhängigkeit von dieser Schwenkbewegung, andererseits nach einer der Entfernungsanzeige dienenden Zeitfunktion abgelenkt. Die Empfängerausgangssp annung wird dem Intensitätssteuerorgan des Braunschen Rohres zugeführt. To solve the problem on which the invention is based, at the same time the distance and direction of several reflective. Display objects, is proposed according to the invention, the retroreflective device with a directional antenna system to provide that. A periolic pivoting movement a, us executes. The electron beam of the Braun tube provided as a display element is then on the one hand dependent from this pivoting movement, on the other hand after a distance display serving Time function distracted. The receiver output voltage becomes the intensity control organ of the Braun tube.
Nach einem älteren Vorschlag wird zwar ebenfalls ein Braunsches. Rohr zur Anzeige von Entfernung und Richtung reflektierender Gegenstände benutzt, in dem der Elektronenstrahl einerseits in Abhängigkeit von der jeweiligen Winkelstellung des Antennensystems. abgelenkt wird. Die zweite dazu senkrechte Ablenkung des Elektronenstrahles wird jedoch in Abhängigkeit von der einfallenden Feldstärke bewirkt. Die Intensität der einfallenden reflektierten Strahlung gibt bei dem älteren Vorschlag nur einen näherungsweisen Anhalt über die Entfernung der reflektierenden Ziele. Die Anzeige wird nämliche dadurch gefälscht, daß die einfallende Feldstärke und damit die zweite Ablenkung des Elektronenstrahles nicht nur von der Entfernung, sondern außerdem noch von den Reflexionseigenschaften und der Größe des Zieles abhängt. Demgegenüber liefert die Einrichtung nach der Erfindung eine Darstellung der reflektierenden Ziele mit wesentlich genauerer Entfernungsanzeige. According to an older suggestion, there is also a brown beer. Tube used to display distance and direction of reflective objects, in which the electron beam depends on the one hand on the respective angular position of the antenna system. is distracted. The second perpendicular deflection of the electron beam however, it is caused as a function of the incident field strength. The intensity of the incident reflected radiation is only one in the older proposal approximate guide to the distance of the reflective targets. The ad is falsified by the fact that the incident field strength and thus the second Deflection of the electron beam not only from the distance, but also still depends on the reflective properties and the size of the target. In contrast the device according to the invention provides a representation of the reflective Targets with a much more accurate range display.
In dem in der Zeichnung dargestellten Schirmbild eines Braunschen Rohres ist ein Bild wiedergegeben, wie man es bei der Abtastung und Aufzeichnung gemäß der Erfindung erhält. Die stärker gezeichneten Stellen und Y zeigen zwei reflektierende Gegenstände an, deren genaue Lage dadurch zu ermitteln ist, daß der Schirm des Braunscher Rohres mit Marken versehen. wird, die in der einen Koordinate den verschiedenen Entfernungen und in der anderen Koordinate den verschiedenen Richtungen entsprechen. In the screen image of a Braunschen shown in the drawing Rohres is an image reproduced as one would when scanning and recording obtained according to the invention. The more heavily drawn areas and Y show two reflective ones Objects, the exact location of which can be determined by the fact that the Braunscher's umbrella Mark the tube. will that in the one coordinate the different Distances and in the other coordinate correspond to the different directions.
In dem dargestellten Beispiel wurde angenommen, daß es sich um eine Helisteuerung handelt, d. h. auf dem Schirm werden die reflektierenden Gegenstände hell auf dunklem Grund erscheinen. In the example shown, it was assumed that it is a Helicopter control acts, d. H. on the screen are the reflective objects appear light on a dark background.
Es ist aber auch möglich, den nicht gesperrten Elektronenstrahl des Braunschen Rohres nur dann zu sperren, wenn im Empfänger Impulse ankommen. In diesem Fall erscheinen die reflektierenden Gegenstände dunkel auf hellem Grund.But it is also possible to use the unlocked electron beam of the Braunschen Rohres to block only when pulses arrive in the receiver. In this In this case, the reflective objects appear dark on a light background.
