Abstract

Summary form only given. For the proposed algorithm it is essential that the SAR (synthetic aperture radar) data are transformed to the range-Doppler domain prior to range compression. In this domain a two-dimensional phase function is multiplied with the data. This phase function produces a slight, space-variant mean frequency shift of the range chirps. This causes a perfect range cell migration correction (RCMC) by the following range compression step. This allows the range compression task to be used to perform the RCMC. Hence, the range chirp serves as an interpolation kernel of a length of several hundred samples.
