Abstract: The cause of azimuth base-line is described based on the characteristic of formation-flying satellites based InSAR system.The correcting method of phases is proposed,and the phase is produced by azimuth base-line.On the basis of this method,the phase correction of InSAR system of formation-flying satellites in the normal instance and the influence to the accuracy of InSAR DEM are analyzed.
