%X In this paper, the focusing has been on spatial interpolation in correcting atmospheric effects using Interferometric SAR based on external data. Several factors have been discussed separately by using both simulated data and GPS data. The results indicate that the inverse distance weighted and kriging interpolation methods are more suitable than the function method and statistical method. And the validity of calibration is influenced by the type and quality of external data. When the external data is precise and regular, the result will be the best. Moreover, the improved interpolation methods by incorporating terrain elevation information have proved to be better.
