Performance Analysis of Bistatic Interferometer Based on Spaceborne Sar

Abstract

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.

DEM generation using bistatic interferometry: High-coherence pixel selection and residual reference phase compensation

“…They commenced the first experiment at the end of 2005, and have successfully acquired the DEM. In China, the Institute of Electronics of the Chinese Academy of Sciences (IECAS) and the National University of Defense Technology (NUDT) have also paid attention on the research of bistatic spaceborne/stationary SAR [10][11][12][13]. Apart from that, Beijing Institute of Technology started to research the bistatic spaceborne/stationary SAR in 2009 [14][15][16][17].…”
