Abstract

An important question with respect to the performance of the interferometric cartwheel and similar bistatic SAR systems, is whether the ambiguities combine coherently and introduce artifacts in the resulting interferograms. We here review the theoretical behavior of range and azimuth ambiguities and extend the description to the case of non-zero Doppler processing. Simulation results confirm that ambiguities cannot significantly degrade the performance of an L-band interferometric cartwheel
