-
摘要: 基于卫星编队InSAR系统的卫星编队特点,阐述了在卫星飞行方向(方位向)产生基线的原因,提出了由方位向基线所引起的干涉相位改正方法,分析了一般情况下卫星编队InSAR系统的相位改正情况和对InSAR高程测量精度的影响。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.
