In Fig.l ist eine Linse 18 teilweise aufgeschnitten, um die Anordnung von Hohlleitern PL nach der Hauptanmeldung 13 bis 17, zu verdeutlichen, Diese Hohlleiter werden über ein gemeinsames Doppler-Speisesystem 10 und eine Anzahl Speisehohlleiter 19-23 parallel angeregt. Die Hohlleiter FL strahlen über ihre, halbkreisförmigen Aperturen und die toroidförmige Luneberg-Linse ihre Energie ab. Durch die Kombination halbkreisförmige Apertur-Linse wird eine geeignete. "Ring"-Phase zur Erzeugung eines fokussierten Strahlungsdiagrammes in der Elevationsrichtung bei verschiedenen Azimutwinkeln erzeugt. Wie in der DT-OS 21 62 068 beschrieben, entsteht das Strahlungsdiagramm in'einer Azimutebene aus einer Anzahl sich überlappender Einzelstrahlen* DieIn Fig.l a lens 18 is partially cut open to the arrangement of waveguides PL according to the main application 13 to 17, To clarify, these waveguides are via a common Doppler feed system 10 and a number of feed waveguides 19-23 stimulated in parallel. The waveguides FL radiate through their, semicircular ones Apertures and the toroidal Luneberg lens release their energy. The combination of a semicircular aperture lens becomes a suitable one.

von den Hohlleitern PL ausgestrahlte Strahlung wird durch die Linse bei jeweils verschiedenen, diskreten Azimutwinkeln fokussiert. Die Koiärination all dieser Strahlen ergibt das gewünschte Strahlungsdiagramm, das über einen großen Azimutwinkelbereich hinweg in -der ElevationsrichtUng konstante Strahlbreite hat. Die Kombination der Strahlungskeulen der verschiedenen Hohlleiter, z.B. 39 und 40, ist in Fig.4b gezeigt.

Die Fig.4a zeigt einen im Querschnitt."hundeknochenförmigen" Strahlungsverlauf, wie er entsteht, wenn die Strahlung direkt von einem einzelnen Hohlleiter nach der Hauptanmeldung ausgestrahlt wird. . ■ : Radiation emitted by the waveguides PL is focused by the lens at different, discrete azimuth angles. The coordination of all these rays results in the desired radiation diagram, which has a constant beam width over a large azimuth angle range in the direction of elevation. The combination of the radiation lobes of the various waveguides, for example 39 and 40, is shown in FIG. 4b. The individual lobes represent the radiations of the single waveguide 13-14, etc .; from .Fig.! after focusing by the lens 18. FIG. 4a shows a cross-section of a "dog-bone" radiation pattern, as it arises when the radiation is emitted directly from a single waveguide according to the main application. . ■ :
Eine Optimierung der Azimutphas.enfehler zweiter und vierter Ordnung verlangt für die toroidförmige Linse eine relative Dielektrizitätskonstante, von ungefähr 4. Damit erhält man eine nahezu konstante Phase.An optimization of the azimuth phase errors of the second and fourth order requires a relative dielectric constant for the toroidal lens, of about 4. This gives an almost constant phase.

Die toroidförmige Linse muß sich mindestens über den im allgemeinen kreisförmigen Bereich der-Hohlleiter 13 bis 17 erstrecken.
