Abstract :
This paper discusses temporal and phase synchronization in SABRINA, a bistatic system that uses ENVISAT and ERS-2 as transmitters of opportunity. Phase synchronization and pulse alignment is achieved using a dedicated channel that receives a clean signal directly from the satellite. It is studied how to temporally align the acquired data with the satellite orbit using the apparent range migration history.
