First experimental results on multi-angle DVB-S based passive ISAR exploiting multipolar data

This work investigates the potentialities of a passive multidimensional ISAR imaging based on DVB-S transmitters of opportunity. Image fusion methods exploiting diversities in both the spatial and polarimetric domains are introduced, aiming at achieving an image with better quality than the images acquired by the individual observation angles and/or polarimetric channels. An analysis using experimental datasets comprising a passive receiver able to collect signals in both the horizontal and vertical polarizations, a cooperative turning ferry, and an Astra satellite has been provided.
