Abstract

This paper presents the Bistatic Interferometer BAsed on Spaceborne SAR (BIBASS), which is a stratosphere airship-mounted multi-channels receiver, using spaceborne SAR system as transmitters of opportunity. At first, the system overview of BIBASS, including the principle of height measurement, system configuration, and the receiver subsystem, is presented. Then, the Signal-to-Noise Ratio (SNR), resolution and relative height accuracy of BIBASS are analyzed. At last, the synchronization approach and imaging algorithm are discussed as technical challenges.
