Apparatus for measuring the position of a vehicle or a surface thereof
First Claim
1. An apparatus for measuring a position of a vehicle or a surface thereof on a roadway, comprising:
- at least one radar transmitter, which is arranged in a transmitting position above the plane of the roadway and transmits radar beams downwardly,a plurality of radar receivers, which are distributed above the plane of the roadway in different receiving positions at distances from one another, receive reflections of the radar beams from beneath, and each convert said reflections into a received signal, andan evaluation device, which is connected to the radar transmitter and the radar receivers and is configured to compare with one another signal strengths of the received signals of the different radar receivers and thereby determine at least one radar receiver which has a weaker or a strongest received signal and measure said position of the vehicle or the surface thereof from the transmitting position as well as from the receiving position of the at least one determined radar receiver.
