Claim 15:
16. A method for determining direction information for at least one target object in a radar system for a vehicle, the method comprising:
providing the first detection information by at least two receive antennas of the radar system, the first detection information being specific for a first radar signal transmitted by a first transmit antenna of the radar system;
providing second detection information by the at feast two receive antennas of the radar system, the second detection information being specific for a second radar signal transmitted by a second transmit antenna of the radar system;
performing a first angle determination from the first and second detection information to determine a first angle information therefrom, so that the first angle information is specific for the first and second radar signal;
performing a second angle determination from the first or second detection information to determine a second angle information therefrom, so that the second angle information is specific for one of the radar signals;
performing a third angle determination from the first and second detection information to determine a third angle information therefrom; and
performing at least one comparison of the first angle information with the second angle information to detect an ambiguity in the first angle determination for the determination of the direction information,
wherein the first angle determination and the third angle determination are carried out using a MIMO method and the second angle determination is carried out using a SIMO method.
