    • For the detection and suppression of interfering signals in SAR data, a time-domain noisy raw data signal U.sub.T (t) is Fourier-transformed by range lines in raw frequency-domain spectrum U.sub.T (f). The resulting spectrum U.sub.T (f) is law-pass filtered according to a transmission-signal bandwith B.sub.s to yield a useful spectrum U.sub.T (f) and an autocorrelation function (t) of useful spectrum U.sub.T (f) is determined in the time domain. A weighting function w(t) is used to suppress portions of the useful signal in the autocorrelation function (t), thereby intensifying the interfering signal in relation to the autocorrelation function (t). The resulting signal (t) is transformed into a power spectral density (f) and a threshold value m is calculated from the power spectral density (f) with a MADMED function. A final notch filter W.sub.N (f) is generated by Fourier-transforming the ideal notch filter frequency response W.sub.N ideal (f).
