In a radar system, which is used particularly in motor vehicles, the angle at which a detected radar target is located are determined by providing that echo signals of the radar target are picked up via at least two reception channels, and their amplitudes are standardized and compared with standardized values, stored in memory, of a duplex antenna graph of the radar system.

[ We claim:] [1.] A method for determining an azimuth and/or elevational angle at which a radar target is located relative to a reference system with a multiple-beam radar system generating at least two radar beams, said method comprising the steps of:a) receiving an echo signal from said radar target produced by each of said radar beams in said multiple-beam radar system;b) standardizing amplitudes of each of said echo signals received by said multiple-beam radar system to form standardized amplitudes;c) storing a standarized antenna graph for each of said radar beams, said standardized antenna graph comprising graph values indicative of a functional relationship between said standardized amplitude of said echo signal and said angle, in a memory of a computer;d) comparing the standardized amplitudes of respective ones of said echo signals with the graph values of the respective standarized antenna graphs stored in said memory for said radar beams to obtain comparison results for each of said radar beams;e) linking the comparison results which were determined during the comparing of step d) for at least two of said radar beams together to form combined comparison results; andf) determining a final value of said angle at which said radar target is located from said combined comparison results by means of a minimum or maximum criterion.
