Description

Die Erfindung betrifft ein für Sendung und Empfang verwendbares Radarantennensystem zum Erzeugen zweier Richtdiagramme mit annähernd gleichem Ursprung und mit überwiegend gleicher Hauptrichtung, welches zum Erzeugen des einen Richtdiagramms ein nach dem Cassegrain-Prinzip arbeitendes Richtantennensystem, das im wesentlichen aus einem Primärstrahler, einem Hilfsreflektor und einem Hauptreflektor besteht, und zum Erzeugen des anderen Richtdiagramms eine Reflektorantenne enthält, deren Reflektor aus der reflektierend ausgebildeten Rückseite des Hilfsreflektors besteht. The invention relates to a radar antenna system that can be used for transmission and reception for generating two directional diagrams with approximately the same origin and predominantly same main direction, which is used to generate the one directional diagram one after the Directional antenna system working on the Cassegrain principle, which essentially consists of a Primary radiator, an auxiliary reflector and a main reflector consists, and for generating of the other directional diagram contains a reflector antenna whose reflector is made of the there is a reflective rear side of the auxiliary reflector.

Ein derartiges Antennensystem ist bekannt. Such an antenna system is known.

Der Erfindung liegt die Aufgabe zugrunde, dieses bekannte Antennensystem für den Einsatz bei der Fernortung von Flugzielen, die beispielsweise Interkontinentalraketen vom »ICBM«-Typ oder auch taktische Raketen sein können, zu verbessern. The invention is based on the object of this known antenna system for use in the remote location of flight targets such as ICBMs of the "ICBM" type or tactical missiles.

Die Erfindung besteht darin, daß das Cassegrain-Richtantennensystem als Empfangsantenne des Radarantennensystems und die Reflektorantenne als dessen Sendeantenne vorgesehen ist und daß vor der Reflektorantenne ein in an sich bekannter Weise bemessenes elektrisches Linsensystem derart angeordnet ist, daß die zwei Richtdiagramme auch größenmäßig miteinander übereinstimmen. The invention is that the Cassegrain directional antenna system as the receiving antenna of the radar antenna system and the reflector antenna as its Transmission antenna is provided and that in front of the reflector antenna a known per se Wisely sized electrical lens system is arranged such that the two directional patterns also match each other in terms of size.

Vorteilhaft beim erfindungsgemäßen Radarantennensystem ist die günstige Sender-Empfänger-Entkopplung einer dieses Antennensystem benutzenden Radaranlage, deren Reichweite dadurch gesteigert wird. In manchen Anwendungsfällen der Erfindung kann auf eine sonst übliche besondere Sender- Empfänger-Entkopplungseinrichtung verzichtet werden. The advantageous aspect of the radar antenna system according to the invention is the favorable one Transmitter-receiver decoupling of a radar system using this antenna system, the range of which is increased as a result. In some applications of the invention can access an otherwise customary special channel Receiver decoupling device dispensed with will.

Besonders vorteilhaft ist auch in vielen Fällen zur Kompensation des störenden Einflusses der Reflektorantenne auf das Richtdiagramm des Cassegrain-Richtstrahlersystems die Anwendung einer weiteren an sich bekannten elektrischen Linse, die ähnlich einer Schmidt-Optik wirkt. Compensation is also particularly advantageous in many cases the disturbing influence of the reflector antenna on the directional diagram of the Cassegrain directional antenna system the use of a further known electric lens, which is similar to a Schmidt-Optik works.
