Comparisons of MIMO SAR antenna arrangements in wide-swath remote sensing

This paper compares four elevation multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) antenna arrangements for wide-swath remote sensing. The signal models and range ambiguity function to signal ratio performance are comparatively compared, along with numerical results. It is shown that, when compared with conventional single-antenna SAR and existing multichannel SAR techniques, MIMO SAR indeed provides a potential solution for wide-swath remote sensing.
