Analysis of bistatic tomography for SAOCOM-CS and Sentinel-1 CS missions

In view of the ESA-CONAE SAOCOM-CS L-band bistatic SAR mission this paper will present, analysis of geometric parameters impact on tomographic processing, discussing questions related to vertical resolution, baseline sampling and interferometric phase calibration in the context of bistatic acquisitions. L-band tomographic processing experiments on real data will be also presented exploiting available ESA SAR airborne campaign images. The amount of computational speed improvement when performing the tomographic algorithms in parallel environment will be also addressed. Furthermore, specific analysis concerning the extension to a possible similar bistatic mission for Sentinel 1 C-band data will be also addressed addressing the TOPS mode impact on tomographic processing.
