Abstract

Vorgeschlagen wird eine Vorrichtung zur Justage der Hauptstrahlrichtung eines Radarsensors. Insbesondere beim Einsatz eines Radarsensors in Fahrzeugen, vorteilhafterweise in Form eines Abstandssensors zur adaptiven Geschwindigkeitsregelung, ist es notwendig, nach der Montage des Radarsensors am Fahrzeug die Hauptstrahlrichtung des Radarsensors exakt auf die Fahrzeuglängsachse auszurichten. Dies geschieht mit der erfindungsgemäßen Vorrichtung, indem eine dielektrische, vorzugsweise planparallele Platte, die zwischen der dielektrischen Linse und der Radarquelle angeordnet ist, positioniert wird.
Durch das Positionieren dieser dielektrischen Platte, ist es möglich, die Hauptstrahlrichtung des Sensors so zu justieren, dass diese parallel zur Fahrzeuglängsachse ausgerichtet wird.

A device for adjusting the main beam direction of a radar sensor is proposed. In particular when using a radar sensor in vehicles, advantageously in the form of a distance sensor for adaptive speed control, it is necessary to align the main beam direction of the radar sensor exactly with the vehicle's longitudinal axis after mounting the radar sensor on the vehicle. This is done with the device according to the invention by positioning a dielectric, preferably plane-parallel plate, which is arranged between the dielectric lens and the radar source.
By positioning this dielectric plate, it is possible to adjust the main beam direction of the sensor so that it is aligned parallel to the longitudinal axis of the vehicle.
