Abstract :
This paper presents the performance analysis of Bistatic Interferometer BAsed on Spaceborne SAR (BIBASS). As a bistatic system with general configuration, the system response of BIBASS is azimuth/range dependent. Taking into account this peculiarity, the appropriate theoretical framework is developed to make a more accurate evaluation of the performance of BIBASS. Firstly, the interferometric features are studied. Then, considering all kinds of de-correlation factors, a comprehensive investigation of coherence of such a system is conducted, followed by the relative height accuracy analysis. The theoretical analysis and simulation show that BIBASS, with the ability of high-precision height measurement, can be widely applied as a novel remote sensing measurement system.
