Automobile-based Bistatic SAR processing and experimental results

In recent years, the interest in bistatic synthetic aperture radar (SAR) has rapidly increased and many bistatic SAR models and processing methods are presented. But some technical problems of bistatic SAR, such as synchronization (in both time and frequency) and the imaging processing of bistatic raw data, have not been resolved sufficiently. To verify bistatic SAR system synchronization plan and imaging processing algorithm, the University of Electric Science and Technology of China (UESTC) developed an Automobile-Based Bistatic SAR system because of its convenience, and carried out a series of experiments. Comparing with airborne monostatic SAR imaging processing, some special problems should be considered. In this paper, we introduce the Automobile-based Bistatic SAR system and discuss the corresponding imaging processing method.
