57 Zusammenfassung AB [EN] A continually adapted pulse-to-pulse shift, performed in the azimuth direction, of the phase center which is electrically active on the side of the transmitting antenna (Tx; Tx1, Tx2, Tx3), in connection with the SAR antenna control of a multi-aperture SAR system is designed such that, in the case of an existing pulse repetition frequency (PRF) due to the likewise shifted position of the effective phase center of the entire antenna (Tx; Tx1, Tx2, Tx3; Rx; Rx1, Rx2, Rx3), a compensation or complete correction of non-equidistant scanning in the azimuth direction is achieved. The principle of the pulse-to-pulse shift of the position of the effective phase center of the antenna for achieving the best possible equidistant scanning can be expanded to the side of the receiving antenna (Rx; Rx1, Rx2, Rx3) and to multi-aperture antennas. The technological solution proposed by the invention can be advantageously combined with a subsequent digital beam formation on the receiving antenna side.
