Abstract

Bei dieser Vorrichtung zum gerichteten Aussenden und zum Empfangen von Ultraschall ist ein trogartiger Reflektorschirm (1) vorgesehen, der quer zu seiner Längsrichtung ein parabelförmiges Schnittprofil hat. In diesem Reflektorschirm (1) sind in Reihe mehrere Ultraschallsender und -empfänger (4) auf Abstand jeweils im Bereich der Scheitellinie des Schnittprofils angeordnet. Unmittelbar vor den Ultraschallsendern (4) ist innerhalb des Reflektorschirms (1) eine Reflektorleiste (7) angeordnet, die symmetrisch zur Axialebene (8) des Reflektorschirms (1) angeordnet, verlauft. Auf diese Weise wird eine breite, bandförmige Schallkeule erzeugt, die durch zwei im wesentlichen parallel zueinander verlaufende Linien begrenzt ist, die ein gutes Erfassen von Hindernissen unabhängig von der jeweils vorliegenden Seitenposition bezüglich der Schallquelle ermöglicht. In this device for directional transmission and Receiving ultrasound is a trough-like reflector screen (1) provided that a parabolic transverse to its longitudinal direction Has cutting profile. In this reflector screen (1) are several ultrasonic transmitters and receivers (4) in series Distance in each case in the area of the apex line of the cutting profile arranged. Immediately in front of the ultrasonic transmitters (4) a reflector strip (7) is arranged inside the reflector screen (1), which are arranged symmetrically to the axial plane (8) of the reflector screen (1), passed. In this way, a broad, ribbon-shaped Sonic beam generated by two essentially lines running parallel to each other is limited, the a good grasp of obstacles regardless of each present page position with respect to the sound source enables.
