In a method for azimuth scaling of SAR data without interpolation, raw SAR data in azimuth are multiplied with a phase function H5(fa;ro), where fa denotes the azimuth frequency and ro denotes the range to a target point, and where a desired scaling factor is entered into the phase function. An azimuth modulation of the SAR data is subsequently adapted with the phase function H5(fa,ro) to that of a reference range, in a manner so that the azimuth modulation no longer depends on the range. In a last step of the process, a quadratic phase modulation is performed in the azimuth so that, in order to attain an azimuth processing with a very high phase accuracy, the azimuth frequency modulation becomes exactly linear.
