A synthetic aperture radar method for remote sensing of the surface of the Earth by means of a radar device on a flying object moving in an azimuth direction above the surface of the Earth, wherein the radar device includes an array of antenna elements for transmitting radar pulses in a transmitting operation and for receiving radar echoes of these radar pulses reflected at the surface of the Earth in a receiving operation. A calibration mode is carried out in which

The present disclosure relates to a method for computer-implemented processing of SAR raw data, which comprises radar echoes from radar pulse. An interference radar echo and an interference pulse are associated with a respective radar pulse, wherein the interference pulse and the respective radar pulse have orthogonal waveforms. SAR raw data are focused by a first focusing on the interference pulses including a range compression and an azimuth compression, to obtain first focused data, where a filtering is used for the range compression of a respective radar pulse, which filtering is matched to the waveform of the associated interference pulse. Thereafter, the first focused data undergo a signal suppression, which at least partially suppresses the interference radar echo, as a result of which second focused data are obtained. These second focused data finally undergo a defocusing including range decompression and azimuth decompression to obtain modified SAR raw data.
