Abstract:
1. A method for determining angular placement of at least one radar target by means of radar using an antenna arrangement, which has: a switched transmission antenna array with a plurality of transmission antennas, which correspondingly radiate a radar transmission signal in a predetermined switching sequence one after the other; a first receiving antenna and a second receiving antenna for receiving the radar signals radiated by the transmission antenna arrays and reflected by the at least one radar target, the method comprising the steps of: receiving a first set of received signals by the first receiving antenna during the switching sequence of the transmission antenna array; receiving, simultaneously to the receiving of the first set of received signals by the first receiving antenna, a second set of received signals by the second receiving antenna during the switching sequence of the transmission antenna array; and determining the angular position of the at least one radar target from the first set and the second set of received signals using an ESPRIT method.
