Abstract: The invention relates to a device (10) for detecting a vehicle, especially an aircraft (A), on an airport runway (R), especially a take-off or landing strip, a taxi strip or in the ramp region, said device comprising at least one radar sensor (11) which is arranged in the region of the runway (R) and used to scan a spatial detection region (E) by means of a radar beam. The fact that the detection region (E) comprises two lobe-shaped partial regions (E1, E2) extending horizontally over the runway (R) and transversally to the direction of travel (V) of the vehicle (A), and the radar sensor (11) is designed to scan the detection region (E) by means of microwaves, enables vehicles moving on runways to be detected with higher measuring precision, higher sensor reliability and using a robust measuring principle.
