A method for computer-aided processing of SAR raw data (RD) which includes radar echoes of radar pulses (RP) which were emitted by a radar device on at least one flying object moving in an azimuth direction (x) above the earth's surface (GR), wherein the radar echoes of the radar pulses (RP) were received and detected by the radar device and wherein the SAR raw data (RD) contains data samples for a plurality of range positions for each radar pulse (RP), wherein the range positions represent different distances (R) between the earth' s surface (GR) and the azimuth direction (x), wherein an interference radar echo and an interference pulse are associated with a respective radar pulse (RP), wherein the interference radar echo is a radar echo of the interference pulse for a first range position and the interference radar echo is received by the radar device simultaneously with a radar echo of the respective radar pulse (RP) for a second range position, wherein the interference pulse is a different radar pulse (RP) than the respective radar pulse (RP) and wherein the interference pulse and the respective radar pulse (RP) have orthogonal waveforms, characterized in that a) the SAR raw data (RD) is focused by means of a first focusing (FC1) on the interference pulses associated with the respective radar pulses (RP), thereby obtaining first focused data (DA1) wherein a range compression (RC1) and an azimuth compression (AC1) are carried out during the first focusing (FC1), and in the process, a filtering (FI1) is applied for the range compression (RC1) of a respective radar pulse (RP), said filtering being adapted to the waveform of the associated interference pulse, b) the first focused data (DA1) is subjected to a signal suppression (SU) which at least partially suppresses the associated interference radar echo for each radar pulse (RP), whereby second focused data (DA2) is obtained; c) the second focused data (DA2) is subjected to a defocusing (DF), whereby modified SAR raw data (RD') is obtained, wherein during the defocusing (DF) a range decompression (RDE) and an azimuth decompression (ADE) are carried out, which are inverse to the range compression (RC1) and the azimuth compression (AC1) of the first focusing (FC1). a) the SAR raw data (RD) is focused by means of a first focusing (FC1) on the interference pulses associated with the respective radar pulses (RP), thereby obtaining first focused data (DA1) wherein a range compression (RC1) and an azimuth compression (AC1) are carried out during the first focusing (FC1), and in the process, a filtering (FI1) is applied for the range compression (RC1) of a respective radar pulse (RP), said filtering being adapted to the waveform of the associated interference pulse, b) the first focused data (DA1) is subjected to a signal suppression (SU) which at least partially suppresses the associated interference radar echo for each radar pulse (RP), whereby second focused data (DA2) is obtained; c) the second focused data (DA2) is subjected to a defocusing (DF), whereby modified SAR raw data (RD') is obtained, wherein during the defocusing (DF) a range decompression (RDE) and an azimuth decompression (ADE) are carried out, which are inverse to the range compression (RC1) and the azimuth compression (AC1) of the first focusing (FC1). <EOS>
