| Abstract: | At present, application of interferometric synthetic aperture radar （INSAR） to monitoring surface small deformation or small area deformation is used more and more. According to this satuation, this paper analyzed these error effects in monitoring the surface small deformation with INSAR on heavy rail. At last, some methods to weaken these error＇s effects were presented. |
| Keywords: | Heavy rail interferometric synthetic aperture radar small deformation monitoring error analysis |
