Abstract:: The M_W=6.5 Bam earthquake,taking place on 26th December 2003 in Iran,caused severe surface deformation.This paper described that it monitored the Bam co-seismic deformation fields using the differential interferometric SAR(D-InSAR)technique and ENVISAT ASAR data.Firstly,it introduced the principle of D-InSAR technique.It introduced the method to select proper D-InSAR data pairs.Then we used ENVISAT ASAR data to carry out 3-pass D-InSAR test in the Bam earthquake.It introduced the procedure of data processing of D-InSAR in detail.We successfully got the Bam co-seismic deformation field.We carried out interpretation and analysis for the deformation field.We generated the profiles and the isoline map according to the deformation map.We also determined the location,distribution and area of the serious destruction region caused by the Bam earthquake according to the coherence map.
