Abstract:
This thesis is dedicated to the special class of bistatic SAR, where the transmitter is a Global Navigation Satellite System (GNSS) and receiver is fixed on the ground. Such a kind of geometry is suited for ground deformation monitoring. The employment of such a navigation satellite brings many advantages, such as shorter satellite revisit time (8-9 days) compared to imaging radar such as Envisat (35days). Moreover, due to large number of satellites deployed (at least 4 satellites could be seen at any time), persistent monitoring of a given area can be achieved from multiple angles simultaneously. This thesis presents research results on the imaging capability of SS-BSAR with GNSS and a stationary receiver. Firstly, the system is outlined and the reason of selecting GNSS as transmitter of opportunity is justified. The power budget and resolution were then analyzed. The end to end signal processing, from received raw data leading to SS-BSAR image, is described. Four experimental data sets acquired at different imaging scenarios are used to test our system hardware and signal processing algorithms mentioned below. It can be seen from the obtained images and associated analysis that such a system has the capability of real scene imaging.
