Abstract

In the context of radar spaceborne imaging, the novel multichannel staggered synthetic aperture radar (SAR) mode represents a promising solution for the mapping of ultrawide swaths with very high azimuth resolution. This paper extends the analysis of multichannel staggered SAR to planar antenna architectures and provides system design examples both for planar and reflector antenna architectures. Furthermore, a first proof of concept using measured data acquired by an experimental ground-based system is provided to demonstrate the approach's feasibility.
