A method for computer-aided processing of SAR data originating from an SAR radar system (SA1, SA2) for remote sensing of the Earth's surface, which comprises at least one emitter and two receivers, wherein the SAR radar system (SA1, SA2) moves in an azimuth direction (x), and, in doing so, the radar echoes of the radar pulses emitted by the at least one emitter and reflected off the Earth's surface are or were received by the two receivers, whereby, for the one receiver, a first data acquisition is obtained, which comprises, for a plurality of azimuth positions in the azimuth direction (x), respectively first samples (d m) for several range positions in a range direction (y) perpendicular to the azimuth direction, and, for the other receiver, a second data acquisition is obtained, which comprises, for a plurality of azimuth positions in the azimuth direction (x), respectively second samples (d s) for several range positions in a range direction (y) perpendicular to the azimuth direction (x), wherein the first and second data acquisitions (DA1, DA2) at least partially cover the same area of the Earth's surface, wherein, in case one or several first samples (d m) are missing, a geometric reconstruction for a respective missing first sample (d m) is carried out, during which the respective missing first sample (d m) is reconstructed from existing second samples (d s) with positions in the second data acquisition, which correspond to reflection positions on the Earth's surface of radar echoes, which contribute to the missing first sample (d m), whereby a third sample (d m,GR) is obtained, wherein the third sample (d m,GR) or a sample derived from the third sample (d m,GR) replaces the missing first sample (d m), characterized in that the geometric reconstruction determines the third sample d m,GR for a given azimuth position of the first data acquisition as follows: d m, GR r m,0 = ∫ dt a, s ∫ dr s ⋅ d s r s t a, s ⋅ exp j ⋅ 4 ⁢ π λ ⋅ r s t a, s ⋅ exp − j ⋅ 4 ⁢ π λ ⋅ r m,0 wherein r m,0 is the range position of the third sample d m,GR; wherein r s represents the range positions according to the second data acquisition and d s (r s) are interpolated second samples of the second data acquisition for the given azimuth position; wherein the integration is carried out over the range positions r s, which correspond to reflection positions on the Earth's surface of radar echoes, which contribute to the missing first sample (d m), and t a,s are the azimuth positions according to the second data acquisition, which are taken up by these reflection positions; wherein λ is the wavelength of the radar waves of the SAR radar system. wherein r m,0 is the range position of the third sample d m,GR; wherein r s represents the range positions according to the second data acquisition and d s (r s) are interpolated second samples of the second data acquisition for the given azimuth position; wherein the integration is carried out over the range positions r s, which correspond to reflection positions on the Earth's surface of radar echoes, which contribute to the missing first sample (d m), and t a,s are the azimuth positions according to the second data acquisition, which are taken up by these reflection positions; wherein λ is the wavelength of the radar waves of the SAR radar system.
