Title:
RADAR SYSTEM WITH ELEVATION MEASURING CAPABILITY
Document Type and Number:
WIPO Patent Application WO/2010/000254
Kind Code:
A3
Abstract:
The invention relates to a radar sensor for recording the environment of a motor vehicle, comprising: transmission means for emitting transmission signals using one or more transmitter antennae; receiving means for receiving transmission signals reflected by objects using one or more receiver antennae; and signal processing means for processing the received signals. The system is characterised in that: received signals are acquired from different combinations of transmitter and receiver antennae, a relative phase centre, which is defined as the sum of the two vectors from a reference point to the phase centres of the respective transmitter and receiver antenna, being assigned to each combination; the transmitter and receiver antennae used in said combination have at least approximately the same emission characteristics and the emission characteristics of said transmitter antennae can be different from those of said receiver antennae; the position of the relative phase centres of said combinations of transmitter and receiver antennae with regard to a spatial direction S that runs perpendicular to a spatial direction R varies periodically with the period length P, when a series of said combinations of transmitter and receiver antennae, which is arranged in the spatial direction R with regard to the position of the relative phase centres, is viewed; and the fact that the signals received from an object have a phase portion that alternates with the period length P over the combinations of transmitter and receiver antennae arranged as above, depending on the angular position of said object in the spatial direction S, is used to make assertions about the position of objects in the spatial direction S.
