This paper deals with the potentialities obtained by splitting the passive antenna of a space-based bistatic SAR into multiple sub-apertures. A preliminary analysis is performed in order to identify the main orbital and system design parameters for a satellite equipped with a multichannel passive radar sensor. The effectiveness of the resulting bistatic system is investigated paying particular attention...
In this paper we investigate the effects of bistatic clutter spectral dispersion on STAP techniques. The use of reduced d.o.f. algorithms is considered since they enable localized training in the range dimension and thus limited effects of clutter non-stationarity. To this aim, the selection of appropriate adaptive degrees of freedom is demonstrated to be a crucial issue. Due to their intrinsic capability...
