Claim 8:
9. The method according to claim 1, wherein the first detection information is determined from the receive signals of the receive antennas such that the first detection information is specific for the first radar signal transmitted by the first transmit antenna of the radar system, reflected on the target object, and delayed by a first transit time, wherein the first detection information has a first phase difference as a function of a direction of the target object and as a function of a distance of the receive antennas to one another, and wherein the second detection information is determined from the receive signals of the receive antennas such that the second detection information is specific for the second radar signal transmitted by the second transmit antenna of the radar system reflected on the target object and delayed by a second transit time, wherein the second detection information has a second phase difference as a function of the direction of the target object and the distance between the receive antennas, and wherein the first detection information has a third phase difference to the second detection information as a function of the direction of the target object and a distance of the transmit antennas to one another, and wherein the first and second phase difference has a phase deviation with respect to one another due to a relative velocity of the target object, which deviation for determining the third phase difference is compensated by measuring the relative velocity in order to carry out the first angle determination using the third phase difference.
