| 摘要 | A method using an antenna arrangement. The antenna arrangement includes a switched transmission antenna array with a number of transmission antennas, which radiate a radar transmission signal one after the other corresponding to a predetermined switching sequence. A first receiving antenna and a second receiving antenna receive the transmitted radar signals and reflected by at least one radar target. A first set of received signals by the first receiving antenna during the switching sequence of the transmission antenna array; receiving a second set of received signals by the second receiving antenna simultaneously with receiving the first set of received signals by the first receiving antenna during the switching sequence of the transmission antenna array; and from these signals the angular position of the at least one radar target based on the first set and the second set of received signals using an ESPRIT method is determined. | ||

| 主权项 | 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. | ||
