Abstract
Description
Die Neuerung betrifft eine Radareinrichtung mit mindestens einer dem Boden zugewandten, zu einer horizontalen Ebene geneigten Sensorfläche.The Innovation relates to a radar device with at least one Floor facing, inclined to a horizontal plane sensor surface.
Bei diesen Radareinrichtungen kann es sich beispielsweise um Mikrowellen-Dopplerradare zur Messung der Geschwindigkeit eines bewegten Objektes, beispielsweise eines Schienenfahrzeuges, relativ zu dem Boden handeln.at These radar devices may, for example, be microwave Doppler radars for measuring the speed of a moving object, for example a rail vehicle, act relative to the ground.
Bei allen gattungsgemäßen Radareinrichtungen tritt das Problem auf, dass die nach unten geneigten Sensorflächen Umweltbelastungen, insbesondere Witterungseinflüssen, ausgesetzt sind, welche durch Dämpfung der Radarstrahlen zum Ausfall der Radareinrichtung führen können. Besonders prekär tritt dieser Effekt bei verschneiten oder vereisten Sensorflächen auf.at All the generic radar devices the problem arises that the downwardly inclined sensor surfaces pollute the environment, especially weather conditions, are exposed, which by damping the radar beams can lead to failure of the radar device. Especially precarious this effect occurs on snowy or icy sensor surfaces.
Der Neuerung liegt deshalb die Aufgabe zugrunde, eine Radareinrichtung anzugeben, bei der der Einfluss von Umweltbedingungen, insbesondere Witterungbedingungen, auf die Funktionsfähigkeit der Radareinrichtung reduziert ist.Of the Innovation is therefore the object of a radar device indicate the influence of environmental conditions, in particular weather conditions, on the functioning of the Radar device is reduced.
Neuerungsgemäß wird die Aufgabe dadurch gelöst, dass die Sensorfläche von einer Schutzhaube mit einer radarstrahldurchlässigen horizontalen Bodenwand umschlossen ist. Durch die horizontale Ausrichtung der radarstrahldurchlässigen Bodenwand ist die Anhaftung von Schnee, Eis, Wasser und Schmutz an dieser Bodenwand gegenüber der Anhaftung an den schrägen Sensorflächen wesentlich verringert. Die Größe der Schutzhaube ist dabei derart bemessen, dass die so genannte Strahlenkeu le, die von der Sensorfläche ausgeht, nicht durch Seitenwände der Schutzhaube beschnitten wird.Innovation is the Task solved by that the sensor surface from a protective hood with a radar beam permeable horizontal Bottom wall is enclosed. Due to the horizontal orientation of the radar beam passing Bottom wall is the attachment of snow, ice, water and dirt opposite to this bottom wall the attachment to the oblique sensor surfaces significantly reduced. The size of the protective hood is dimensioned such that the so-called Strahlenkeu le, the from the sensor surface goes out, not by sidewalls the guard is cropped.
Gemäß Anspruch 2 ist die Schutzhaube im Wesentlichen nasenförmig ausgebildet. Die Schutzhaube kann dabei eine einzige Sensorfläche oder auch mehrere benachbarte Sensorflächen umschließen. Häufig sind zwei mit unterschiedlichen Winkeln zur Horizontalen geneigte Sensorflächen vorgesehen, um eine zweikanalige Funktionsweise zu ermöglichen.According to claim 2, the guard is essentially nose-shaped. The protective hood can have a single sensor surface or enclose several adjacent sensor surfaces. Frequently two sensor surfaces inclined at different angles to the horizontal are provided, to enable a two-channel mode of operation.
Damit sich kein Spritzwasser oder Regenwasser im Inneren der Schutzhaube sammeln kann, sollte diese gemäß Anspruch 3 wasserdicht an den Rändern der Sensorfläche bzw. Sensorflächen befestigt sein. Die Schutzhaube kann beispielsweise angeklebt und/oder unter Nutzung eventuell bereits vorhandener Bohrungen angeschraubt werden. Wasseransammlungen im Inneren der Schutzhaube sind unbedingt zu vermeiden, da diese stark dämpfend auf die Radarstrahlung wirken.In order to no splash water or rainwater inside the protective cover should be able to collect these according to the claim 3 waterproof at the edges the sensor surface or sensor surfaces be attached. The protective hood can for example be glued on and / or bolted using possibly existing holes become. Water accumulation inside the protective cover is essential to avoid, since these strongly dampening up the radar radiation act.
Zusätzlich oder alternativ kann das Innere der Schutzhabe gemäß Anspruch 4 mit radarstrahldurchlässigem Material ausgeschäumt sein.Additionally or Alternatively, the interior of the protection according to claim 4 radarstrahldurchlässigem material foamed be.
Als radarstrahldurchlässiges Material für die Bodenwand der Schutzhaube ist gemäß Anspruch 5 vorzugsweise ein Teflonmaterial vorgesehen. Teflon hat darüber hinaus den Vorteil, dass dauerhafte Anhaftung von radarstrahldämpfenden Partikeln, beispielsweise verharschtem Schnee, kaum auftreten kann.When radar beam permeable Material for the bottom wall of the protective hood is preferably a according to claim 5 Teflon material provided. Teflon also has the advantage that permanent adhesion of Radarstrahldämpfenden particles, for example hardened snow, barely can occur.
