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 presents research results in Space-Surface Bistatic Synthetic Aperture Radar (SS-BSAR) with GNSS non-cooperative transmitters. The experimental-setup used to study the SS-BSAR is described. The signal processing algorithm that will be used to process the data collected from SS-BSAR is also discussed.
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)
