N2 - The ground-based frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) system has achieved good results in deformation monitoring with its high precision, high resolution, flexible viewing angle and other outstanding technical advantages. When performing deformation monitoring, ground-based synthetic aperture radar (GB-SAR) requires high precision that should reach millimeter or sub-millimeter level. Therefore, high phase stability is not only the basis of interferometry but also the guarantee of high precision measurement. However, ground-based FMCW SAR system, like other continuous wave radar systems, is also limited by the limitations of the continuous wave system. The inherent leakage signal enters the radar echo, which affects radar imaging and interferometric deformation measurement. In this paper, the combination of theory and simulation is used to analyze and verify the influence of the coupling signal on the deformation accuracy.
