Description

Die Erfindung geht aus von einer phasengesteuerten Antenne nach dem Oberbegriff des Patentanspruchs 1.The invention is based on a phased array antenna according to the preamble of claim 1

Solche Antennen, insbesondere für Radaranwendungen, sind bekannt, beispielsweise aus den Offenlegungsschriften DE-A 3803779 sowie DE-A 3902739. Die dort beschriebenen Anordnungen bestehen im wesentlichen aus einer Vielzahl von Sende/Empfangsstrahlerelementen, die zeilen- oder matrixförmig angeordnet sind. Diese Sende/Empfangsstrahlerelemente sind über eine Phasenschieberanordnung, ein Verteilernetzwerk sowie einen Sende/Empfangsumschalter, einen Zirkulator, an eine an sich bekannte Sende/Empfangsanordnung angeschlossen. Dabei dient das Verteilernetzwerk sowie die Phasenschieberanordnung zur elektronischen Formung und/oder Schwenkung einer Sende/Empfangskeule. Durch den Sende/Emp fangsumschalter wird eine Entkopplung der Sende- und Empfangssignale erreicht.Such antennas, in particular for radar applications, are known, for example from the published patent applications DE-A 3803779 and DE-A 3902739. The described there Arrangements consist essentially of a multiplicity of transmitting / receiving radiator elements, which are arranged in line or matrix form. This Transceiver elements are via a phase shifter arrangement Distribution network and a send / receive switch, a circulator, to a connected to known transmission / reception arrangement. The distribution network serves this purpose and the phase shifter assembly for electronic forming and / or pivoting a transmitting / receiving lobe. Through the send / Emp switcher a decoupling of the transmit and receive signals is achieved.

Eine weitere Antennenanordnung wird in US 3,906,502 beschrieben. Diese Anordnung weist als zusätzliche Merkmale einen Wellenleiter auf, welcher in seiner Längsrichtung mehrere Ein-/Auskoppelstellen zur Ein-/Auskopplung der in dem Wellenleiter führbaren Wellen umfaßt. Diese Ein-/Auskoppelstellen sind mittels Verbindungswellenleitern mit dem Verteiler- und Phasensteller-Netzwerk verbunden.Another antenna arrangement is described in US 3,906,502. This arrangement has as additional features a waveguide, which in its longitudinal direction several input / output coupling points for coupling in / out in the waveguide includes executable waves. These coupling / decoupling points are by means of connecting waveguides connected to the distributor and phaser network.

Eine derartige Anordnung ist in nachteiliger Weise technisch aufwendig, da eine Vielzahl genauer Bauelemente erforderlich sind.Such an arrangement is disadvantageously technically complicated, since a variety exact components are required.

Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße Anordnung dahingehend zu verbessern, daß eine Verwendung technisch aufwendiger Bauelemente, insbesondere des Zirkulators, entfällt.The invention is therefore based on the object, a generic arrangement to improve that a use of technically complex components, in particular the circulator, is eliminated.

Diese Aufgabe wird gelöst durch die im Patentanspruch 1 angegebenen Merkmale. Vorteilhafte Ausgestaltungen und/oder Weiterbildungen sind den weiteren Ansprüchen entnehmbar. This object is achieved by the features specified in patent claim 1. Advantageous embodiments and / or further developments are the further claims removable.

Die Erfindung beruht auf der Verwendung einer Serien-Speiseleitung, die mehrere Ein/Auskoppelstellen zur Ein/Auskopplung der verwendeten Sende/Empfangssignale besitzt und außerdem zwei Tore zur Ankopplung der Sende- sowie der Empfangsanordnung. Mit einer solchen Serien-Speiseleitung und einem daran angekoppelten verteiler- und Phasenstellernetzwerk ist in überraschender Weise ein Sende/Empfangsumschaltung möglich, ohne daß ein gesonderter Sende/Empfangsumschalter, insbesondere ein Zirkulator, nötig ist. Eine Serien-Speiseleitung besteht aus einem für die verwendeten Sende/Empfangswellenlängen geeigneten Wellenleiter, beispielsweise einem Hohlleiter, bei dem in der Ausbreitungsrichtung der geführten Welle in vorgebbaren, äquidistanten Abständen eine vorgebbare Anzahl von Koppelstellen, beispielsweise Koppelschlitze, angeordnet sind. Damit ist es beispielsweise im Sendefall möglich, ein in dem Wellenleiter geführtes Sendesignal in eine vorgebbare Anzahl, welche der Anzahl der Koppelstellen entspricht, von Einzel-Sendesignalen mit vorgebbaren Sendeleistung aufzuteilen. Diese ist insbesondere von der Ausgestaltung der Koppelstellen abhängig, was einem Fachmann geläufig ist. Diese Einzel-Sendesignale, die beispielsweise einer vollständigen Zeile von Strahlerelementen zugeordnet sind, werden dann über Verteiler- und Phasenstellernetzwerke den einzelnen Sende/Empfangsstrahlerelementen zugeleitet.The invention is based on the use of a series feed line, the more On / Off coupling points for coupling / uncoupling the used transmit / receive signals has and also two gates for coupling the transmitting and the receiving device. With such a series feed line and a coupled thereto Distributor and phaser network is surprisingly a transmit / receive switch possible without a separate send / receive switch, especially a circulator, is necessary. A standard supply line consists of one for the used transmission / reception wavelengths suitable waveguide, for example a waveguide in which in the propagation direction of the guided Wave in predeterminable, equidistant intervals a predetermined number of coupling points, For example, coupling slots are arranged. That's it, for example in the transmission case, a guided in the waveguide transmission signal in a predetermined Number, which corresponds to the number of coupling points, of individual transmission signals split with predetermined transmission power. This one is special depends on the design of the coupling points, which is familiar to a person skilled in the art is. These single transmit signals, for example, a full line are assigned by radiator elements are then via distribution and phaser networks fed to the individual transmit / receive radiator elements.

Bei der Erfindung wird nun die Erkenntnis ausgenutzt, dass die Funktion einer solchen Serien-Speiseleitung, insbesondere die Ausbreitungsrichtung der geführten Welle, von den an den Koppelstellen vorhandenen Amplituden- und/oder Phasenbeziehungen abhängt.In the invention, the knowledge is now exploited that the function of such Series feedline, in particular the propagation direction of the guided Wave, from the present at the coupling points amplitude and / or phase relationships depends.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf eine schematisch dargestellte Figur näher erläutert. Diese zeigt schematisch dargestellte Verteilernetzwerke.The invention is described below with reference to an embodiment with reference explained in more detail to a schematically illustrated figure. This shows schematically illustrated distribution networks.

Fig. 1 zeigt einen Wellenleiter WE, beispielsweise einen Hohlleiter mit rechteckförmigem Querschnitt für den 5-GHz-Bereich. Der Wellenleiter WE hat zwei Tore T1, T2 und eine vorgebbare Anzahl von Schlitzen S1 bis Sn, wobei n eine vorgebbare ganze Zahl ist. Die Schlitze S1 bis Sn sind als Ein-/Auskoppelschlitze ausgebildet für die im Wellenleiter WE geführte Welle (Wellenlänge A) und haben in der Längsrichtung des Wellenleiter WE (Ausbreitungsrichtung der Welle) eine Abstand von λ/2. An jedem der Ein-/Auskoppelschlitze S1 bis Sn ist ein zugehöriger Verbindungswellenleiter VW1 bis VWn (Verbindungshohlleiter) angekoppelt. Diese führen zu nicht dargestellten, aber aus den eingangs genannten Druckschriften an sich bekannten Phasensteller-Netzwerken, die in mit PHN bezeichnet sind. An diese sind dann, entsprechend den eingangs genannten Druckschriften, die Sende/Empfangsstrahlerelemente angeschlossen. Wird nun beispielsweise ein Sendesignal als fortlaufende Welle in das Tor 1 eingekoppelt, so werden an den Ein-/Auskoppelschlitzen S1 bis Sn Anteile ausgekoppelt und über die Verbindungswellenleiter VW1 bis VWn sowie die Phasensteller an die Sende/Empfangsstrahlerelemente geleitet. Mittels der Phasensteller ist dann in bekannter Weise eine Schwenkung der Sendekeule (Sendecharakteristik) möglich.Fig. 1 shows a waveguide WE, for example a waveguide with a rectangular Cross section for the 5 GHz range. The waveguide WE has two ports T1, T2 and a predeterminable number of slots S1 to Sn, where n is a predefinable integer Number is. The slots S1 to Sn are formed as input / Auskoppelschlitze for in the Waveguide WE guided wave (wavelength A) and have in the longitudinal direction of the Waveguide WE (propagation direction of the wave) a distance of λ / 2. At each the input / output slots S1 to Sn is an associated connection waveguide VW1 to VWn (connecting waveguide) coupled. These lead to not shown, but from the cited references to known phaser networks, which are designated in PHN. These are then, accordingly the publications mentioned above, the transmitting / receiving radiator elements connected. Now, for example, a transmission signal as a continuous Wave coupled into the gate 1, so are at the input / Auskoppelschlitzen S1 to Sn shares decoupled and via the connecting waveguide VW1 to VWn and the phase adjuster is routed to the transmit / receive radiator elements. By means of the phaser is then in a known manner, a pivoting of the transmitting lobe (transmission characteristic) possible.

Im Empfangsfall wird nun das von den Sende/Empfangsstrahlerelemente empfangene Signal, beispielsweise die zu dem Sendesignal gehörenden Echosignale, über die Phasensteller des Phasen-Netzwerkes sowie die Verbindungswellenleiter VW1 bis VWn in den Wellenleiter WE geleitet. Es ist nun vorteilhafterweise möglich, die Phasensteller in diesem Empfangsfall derart einzustellen, daß das in dem Wellenleiter WE entstehende Empfangssignal an dem zweiten Tor T2 auskoppelbar ist. An dem ersten Tor T1 entsteht allenfalls ein vernachlässigbarer (Reflexions-)Anteil. Das an dem zweiten Tor T2 entstandene Empfangssignal wird dann in an sich bekannter Weise, beispielsweise über Hohlleiter, an einen (Radar-)Empfänger geleitet und dort ausgewertet.In the reception case, the received from the transmitting / receiving radiator elements is now Signal, for example, belonging to the transmission signal echo signals, via the Phase adjuster of the phase network and the connecting waveguides VW1 to VWn guided in the waveguide WE. It is now advantageously possible, the phaser in this receiving case to adjust such that in the waveguide WE resulting receiving signal to the second port T2 can be coupled out. To the At first goal T1 arises at most a negligible (reflection) share. The on The received signal resulting from the second gate T2 is then known per se Way, for example via waveguide, directed to a (radar) receiver and there evaluated.

In der beschriebenen Weise ist also eine Trennung des Sendesignals, das in das erste Tor T1 eingekoppelt wird, von dem Empfangssignal, das aus dem zweiten Tor T2 ausgekoppelt wird, möglich, ohne daß ein zusätzlicher Sende-/Empfangsumschalter, beispielsweise ein Zirkulator, verwendet wird. Der beschriebene Sende-/Empfangs-Umschaltvorgang erfolgt allein durch eine Verstellung der Phasensteller um Werte, die von der Phasenprogression der Serien-Speiseleitung und dem einzustellenden Elevations-Schwenkwinkel der Strahlcharakteristik abhängen; die entsprechende Berechnung ist dem Fachmann geläufig. In the manner described is thus a separation of the transmission signal in the first Tor T1 is coupled from the received signal coming from the second port T2 is possible, without an additional send / receive switch, For example, a circulator is used. The described send / receive switching process takes place solely by an adjustment of the phasors by values, that of the phase progression of the series feedline and the to be set Depend on elevation tilt angle of the beam characteristic; the corresponding calculation is familiar to the expert.

Es ist ersichtlich, dass die beschriebene Anordnung mit einer Vielzahl von Wellenleitern, beispielsweise in sogenannter Stripline- oder Mikrostrip- oder Koaxial-Technologie, herstellbar ist.It can be seen that the arrangement described with a plurality of waveguides, for example in so-called stripline or microstrip or coaxial technology, can be produced.

Bei dem beschriebenen Beispiel müssen lediglich die Phasensteller (Phasenschieber) von Senden auf Empfangen oder umgekehrt umgeschaltet werden. Für derartige Phasenumschaltvorgänge ist eine Vielzahl derzeit üblicher Phasensteller geeignet, beispielsweise Verzögerungsleitungen. Die Erfindung ist besonders vorteilhaft wenn bereits nichtreziproke Phasensteller (Ferrit-Phasenschieber) in der Sende/Empfangsanordnung verwendet werden, da diese Phasensteller bei jedem Sende-/Empfangs-Umschaltvorgang umgeschaltet werden müssen. Bei diesem Umschaltvorgang ist dann die beschriebene zusätzliche Phasenverstellung ohne mehr Aufwand durchführbar.In the example described, only the phasors (phase shifters) need to switch from send to receive or vice versa. For such Phase switching operations is a variety of currently conventional phaser suitable for example, delay lines. The invention is particularly advantageous when already non-reciprocal phase adjuster (ferrite phase shifter) in the transmit / receive arrangement can be used, as these phase shifters each transmit / receive switching have to be switched. In this switching process is then the described additional phase adjustment without more Effort feasible.
