This article presents signal processing algorithms used as a new remote sensing tool, that is passive bistatic SAR with navigation satellites (e.g. GPS, GLONASS or Galileo) as transmitters of opportunity. Signal synchronisation and image formation algorithms are described for two system variants: one where the receiver is moving and one where it is fixed on(More)
This paper investigates the feasibility of Galileo navigation satellites as transmitters of opportunity in passive bistatic synthetic aperture radar (SAR) systems from the perspectives of signal processing and experiment program. Experimental images obtained using a single Galileo channel, E5a or E5b, are presented and analyzed. The paper also puts forward(More)
