Abstract
In an object verification method for use in radar systems for motor vehicles, the distances and relative velocities of located objects are determined on the basis of received radar echoes. The signature of multiple reflections is searched for in the received radar echoes to verify real objects.
Claims10
A method for object verification for use in radar systems for a controlled motor vehicle, comprising:
- transmitting a radar signal from the controlled motor vehicle;
- determining, based on radar echoes received at the controlled motor vehicle, a relative distance and a relative velocity between the controlled motor vehicle and each one of a plurality of located potential objects;
- and
- analyzing the determined relative distances and relative velocities to identify a characteristic signature indicating multiple reflections of the radar signal between the controlled motor vehicle and at least one of the plurality of located potential objects, wherein the characteristic signature is used for object verification.

A driver assistance system for a motor vehicle, comprising:
- a unit for transmitting a radar signal from the controlled motor vehicle;
- an arrangement for determining, based on radar echoes received at the controlled motor vehicle, a relative distance and a relative velocity between the controlled motor vehicle and each one of a plurality of located potential objects;
- and
- an arrangement for analyzing the determined relative distances and relative velocities to identify a characteristic signature indicating multiple reflections of the radar signal between the controlled motor vehicle and at least one of the plurality of located potential objects, wherein the characteristic signature is used for object verification.
