Description

Antennenanordnung zur Erzeugung einer Strahlung für die Durchführung von Flugzeugblindlandungen Das Hauptpatent befaßt sich im besonderen mit der Ausbildung einer mittels sehr kurzer Wallen erzeugten Raumstrahlung, welche zur Festlegung einer Führungsbahn für Flugzeuglandezwecke dient. Gemäß den Merkmalen des Hauptpatents soll der Horizontalschnitt durch das Diagramm der Raumstrahlung in der Landerichtung eine Eins.attelung aufweisen, also eine charakteristische Form besitzen, damit die schräg zur Symmetrieebene dieses Diagramms verlaufende Anflugleitebene dasselbe längs gerader Linien konstanter Feldstärke schneidet. Zur Erzeugung der räumlichen Strahlung sieht das Hauptpatent eine Antennenanordnung vor, welche aus zwei gegenphasig gespeisten Einzelantennen, die in einem Abstand von etwa 3,872 bztv. i,95 A, angeordnet sind, besteht.Antenna arrangement for generating radiation for the implementation of aircraft blind landings. The main patent deals in particular with the formation of spatial radiation generated by means of very short walls, which is used to define a guideway for aircraft landing purposes. According to the features of the main patent, the horizontal section through the diagram of spatial radiation should have a saddle in the landing direction, i.e. have a characteristic shape so that the approach control plane, which runs obliquely to the plane of symmetry of this diagram, intersects the same along straight lines of constant field strength. To generate the spatial radiation, the main patent provides an antenna arrangement which consists of two individual antennas fed in phase opposition, which are spaced approximately 3.872 meters apart. i, 95 A, are arranged.

Diese Antennenanordnung hat die Eigenschaft, daß das gewünschte Raumdiagramm spiegelbildlich erzeugt wird, d. h. daß eine Strahlung in zwei entgegengesetzten Richtungen auftritt. Da es jedoch vielfach erwünscht ist, nur eine einzige Landerichtung festzulegen, wird gemäß der Erfindung Beine diesen Erfordernissen. gerecht werdende Antennenanlage vorgeschlagen.This antenna arrangement has the property that the desired spatial diagram is generated as a mirror image, d. H. that a radiation in two opposite Directions occurs. However, since it is often desired, only one landing direction Establish, according to the invention will meet these requirements. righteous Antenna system proposed.

Erfindungsgemäß dient zur Erzeugung des Raumdiagramms ein Antennensystem, das statt aus zwei Einzelstrahlern aus zwei gegenphasig gespeisten Gruppen von je vier Einzelstrahlern besteht, die in einer Linie derart aufgestellt sind, daß ihre Abstände voneinander innerhalb jeder Gruppe A/q. und die mittlere Entfernung beider Gruppen wieder 3,877 oder auch 1,95.? beträgt.According to the invention, an antenna system is used to generate the spatial diagram, which instead of two individual radiators consists of two anti-phase fed groups of four individual radiators which are set up in a line in such a way that their distances from one another within each group A / q. and the mean distance of both groups again 3.877 or 1.95.? amounts to.

In der Abbildung ist das erfindungsgemäße Antennengebilde dargestellt. Dasselbe besteht aus den beiden in einem mittleren A.bstan,d.d von 3,87A bzw. i,95 A angeordneten, gegenphasig gespeisten Strahlergruppen Ei und E's, wobei jede Strahlergruppe aus den vier Einzelstrahlern e1, e@, @ez, e bzw. e5, e,;, e7, e$ gebildet ist, welche untereinander einen Abstand von @/4 besitzen. Die Speisungsverhältnisse sind durch die ,angeschriebenen Winkelgrade zum Ausdruck gebracht.The antenna structure according to the invention is shown in the figure. The same consists of the two emitter groups Ei and E's, which are fed in phase opposition, and are arranged in a middle distance between 3.87A and i, 95A, each emitter group consisting of the four individual emitters e1, e @, @ez, e and e5, e,;, e7, e $ is formed, which have a distance of @ / 4 from one another. The feed ratios are expressed by the degrees of angles written on.

Form und Tiefe der Einsattelung können durch Variation des Abstandes,d der beiden Strahlergruppen E', und E. beeinflußt werden. In der Abbildung bedeuten D das von dem Antennensystem erzeugte Horizantaldiagramm und LB die Flugplatzgrenzen. Die Anflugrichtung ist durch die Linie G angedeutet.The shape and depth of the saddle can be changed by varying the distance, i.e. of the two emitter groups E ', and E. are influenced. In the figure mean D the horizontal diagram generated by the antenna system and LB the airport boundaries. The direction of approach is indicated by line G.
