Bistatic synthetic aperture radar using GNSS as transmitters of opportunity

[摘要] The thesis summarizes the research on the feasibility investigation of Space-Surface (i.e. a spaceborne transmitter and an airborne receiver) Bistatic Synthetic Aperture Radar (SSBSAR)with a Global Navigation Satellite System (GNSS) which is used as a transmitter of opportunity. The most promising non-cooperative transmitter, among the existing GNSS, for the practical radar applications is the newly introduced European Galileo system. Three main areas are included in the thesis: the system overview, hardware and experimentation, and the experiential results analysis. The system overview discusses the key operation principles (topology, synchronization, etc.) of the proposed radar system and an analysis of the system parameters (power budget, spatial resolution etc.). A hardware was specially developed and the experiments have been conducted to investigate the system feasibility and performance. Synchronisation and image formation algorithms are discussed with the dedication to the proposed radar system. The experimental results, obtained from the synchronisation, stationary receiver and ground moving receiver experiments are presented and analysed in the thesis.
