Abstract
Erfindungsgemäß wird ein mehrstrahliger Radarsensor vorgeschlagen, bei dem eine federnd ausgebildete Halterung für Polyrods in Verbindung mit einem Abstandshalter die Polyrods in einem vorgegebenen Abstand, vorzugsweise im Bereich zwischen 0 mm und 0,2 mm festhält. Die Pfosten 4b der Halterung 4 sind derart ausgebildet, daß ständig eine Federkraft den Abstandshalter 5 gegen die Grundplatte 1 drückt. Die Federkraft ist dabei so gewählt, daß auch bei ungünstigen Betriebsbedingungen, wie Vibration, Schock und Schlag, die Einhaltung des vorgegebenen Abstands a gewährleistet ist.
Description
Die Erfindung geht aus von einem mehrstrahligen Radarsensor
mit einer Halterung für ein Polyrod (Vorfokussierkörper oder
auch Stielstrahler genannt) nach der Gattung des
Hauptanspruchs. Radarsensoren, bei denen zur Vorfokussierung
Polyrods verwendet werden, sind beispielsweise aus der
WO 97/02496 bekannt. Hier wird ein FMCW-Radarsensor für ein
Fahrzeug zur Detektion von Objekten vorgeschlagen, bei dem
beispielsweise drei Sende-/Empfangselemente auf einer
lateralen Struktur eines Mikrowellenstreifenleiters
aufgebracht sind. Im Strahlengang ist vor jedem
Antennenelement zusätzlich ein dielektrischer Stielstrahler
(Polyrod) angebracht, um eine bessere Ausleuchtung der
dielektrischen Linse und somit eine Vorfokussierung zu
erreichen. Es hat sich jedoch herausgestellt, daß eine
einwandfreie Funktion des Stilstrahlers nur dann
gewährleistet ist, wenn diese exakt positioniert sind.
Selbst kleine Abweichung von der idealen Position bewirken
eine Überstrahlung der Linse oder eine Kopplung mit
benachbarten Polyrods.
Aus der DE 197 10 811-A1 ist eine Vorrichtung zum
gerichteten Abstrahlen und/oder Aufnehmen
elektromagnetischer Wellen bekannt. Diese Vorrichtung
besteht aus mindestens einem Antennenelement, einer
dielektrischen Linse und einem dielektrischen Körper
(Polyrod), der zwischen dem Antennenelement und der
dielektrischen Linse angeordnet ist. Dieser dielektrische
Körper dient zur Vermeidung der Überstrahlung der
dielektrischen Linse und zur Vorfokussierung der von dem
Antennenelement abgestrahlten bzw. aufgenommenen
elektromagnetischen Wellen. Zur Vereinfachung der
erforderlichen exakten Justage ist der dielektrische Körper
flächig ausgedehnt und vorzugsweise topfförmig ausgebildet.
Auch in diesem Fall ist eine ungenügende Entkopplung der
elektromagnetischen Wellen anzunehmen, da für alle
Antennenelemente der gleiche dielektrische Körper verwendet
wird.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung
dargestellt und in der nachfolgenden Beschreibung näher
erläutert. Fig. 1 zeigt einen Querschnitt eines
Abstandshalters für ein Polyrod und Fig. 2 zeigt eine
Ansicht von unten.
Fig. 1 enthält aus Gründen der Übersichtlichkeit lediglich
die Elemente, die eine erfindungsgemäße Halterung 4 für die
Polyrods 3 darstellt. Die weiteren Elemente des Radarsensors
sind hinreichend bekannt und müssen nicht näher erläutert
werden.
Wie in der Querschnittszeichnung der Fig. 1 dargestellt
ist, ist auf einer Grundplatte 1 eine Mikrowellenleiter-
Struktur 2 dargestellt, über die drei etwa kegelförmige
Polyrods 3 angeordnet sind. Die Halterung 4 ist dabei so
ausgebildet, daß die Polyrods 3, die mit einem Bückenteil 4a
der Halterung 4 fest verbunden sind, exakt über dem Sende-
/Emfangselementen der Mirkowellenleiter-Struktur 2
angeordnet sind (in Fig. 1 nicht dargestellt).
Erfindungsgemäß ist vorgesehen, den Abstand a zwischen der
Oberfläche der Mikrowellenleiter-Struktur 2 und der
Unterseite der Polyrods 3 in einem Bereich zwischen 0 mm und
0,2 mm festzulegen. Eine Änderung des Abstands a, auch
außerhalb des vorgegebenen Bereichs, ist im Einzelfall
ebenfalls vornehmbar.
Um den Abstand a einzuhalten, ist ein Abstandshalter 5
vorgesehen, der an der Unterseite des Brückenteils 4a an
einer geeigneten Stelle angeordnet ist. Da die Polyrods 3
mit dem Brückenteil 4a fest verbunden sind und darüber
hinaus das Brückenteil 4a relativ massiv ausgestaltet ist,
um eine gegenseitige Relativbewegung der Polyrods 3 zu
verhindern, sind zwischen den Pfosten 4b und dem Brückenteil
4a federnde Bereiche 4c vorgesehen. Die Pfosten 4b sind
gegenüber der Grundplatte 1 in ihrer Länge so bemessen, daß
der Abstandshalter 5 über die federnden Bereiche 4c und dem
Brückenteil 4a beispielsweise gegen die Grundplatte gedrückt
wird. Der Druck ist dabei so bemessen, daß auch unter
ungünstigen Betriebsbedingungen wie Vibration, Schock oder
Stoß die genaue Einhaltung des Abstands a gewährleistet ist.
Eine weitere Verbesserung des Erfindungsgegenstandes besteht
darin, daß an geeigneten Stellen, wie der Fig. 2 entnehmbar
ist, ein oder mehrere weitere Abstandshalter 5 vorsehbar
sind.
Es ist vorgesehen, dem Abstandshalter 5 entweder durch
Einbringen eines geeigneten Materials in die Konstruktion
einzufügen. Alternativ kann der Abstandshalter 5 durch
Prägung oder bei Kunststoffen im Gieß-, Fließ- oder
Preßverfahren ausgeprägt sein. Vorzugsweise wird für die
Halterung 4 ein dielektrisches Material verwendet, das
gegenüber dem Material der Polyrods 3 eine Verminderung der
gegenseitigen Kopplung benachbarter Polyrods 3 begünstigt.
Fig. 2 zeigt eine Ansicht von unten. Wie der Zeichnung
entnehmbar ist, sind die Polyrods 3 durch Bohrungen 6
geführt, die in Reihe angeordnet sind. Um vorzugsweise 90°
hierzu gedreht sind zwei zylinderförmig ausgebildete
Abstandshalter 5 angeordnet. Die Form der Abstandshalter 5
kann unter den gegebenen Randbedingungen beliebig gewählt
werden. Beispielsweise kann sie auch ringförmig um die
Polyrods 3 ausgebildet sein.
