| 摘 要： | 失相干问题是合成孔径雷达干涉测量技术实用化的最大障碍之一,尤其是在D-InSAR处理中,失相干问题更为突出.通过对D-InSAR处理中的各种失相干源进行量化计算,找出了D-InSAR处理中影响SAR像对相位间相干性的主要因素,进而在理论分析的基础上,提出了减小D-InSAR处理中相位失相干的有效方法.

| Abstract: | Decorrelation is one of the most difficult problems in the procedure of making the InSAR tech-nique practicable,especially in the processing of D-InSAR.The primary resource inducing decorrelation between the SAR images in D-InSAR is found out by means of quantizing the various resources of decorrelation.Further more,the effective approach of weakening the decorrelation between the SAR images in D-InSAR is put forward on the basis of theoretical analysis and calculation. |
