Non-cooperative bistatic SAR imaging system: spatial resolution analysis

In this paper we consider a bistatic SAR imaging system which involves a purpose built ground- based or airborne receiver and which utilizes a non- dedicated satellite (e.g. Globalstar or GPS satellites) as the transmitting signal source. We analyse the spatial resolving capability of this non-cooperative bistatic SAR imaging system. In particular, with earth observation applications in mind, we characterize quantitatively the 2-D resolving capability within the ground plane. This is demonstrated via simulations.
