摘要
综述了合成孔径雷达干涉测量(InSAR)技术的研究现状及其在监测地面沉降方面的优势和缺陷。与传统监测方法相比,InSAR技术在地面沉降监测方面主要具有全天候、大范围、高分辨率、高精度等优势,但在实际应用中则会产生去相关问题。探讨了利用该技术监测地面沉降的发展方向,认为应将InSAR与GPS及传统的水准测量等方法结合使用,合理利用各技术之间的互补性。
Synthetic aperture radar interferometry （InSAR） technology is an important developmental direction of microwave remote sensing in recent years,and is applied in monitoring subsidence both at home and abroad. This paper first reviews, briefly, the study of InSAR technology,application and its development in monitoring land subsidence. Then,it summarizes the advantage and disadvantage of InSAR and DInSAR in subsidence measurements. Comparing with traditional method,InSAR and DInSAR in monitoring landslide has many advantages,such as the images can be obtained every times when the SAR satellites pass the area,also,the images have high-resolution and accuracy,etc. However,there will be decorrelation in the course of practical application. Finally,the paper demonstrates that the method of GPS-InSAR integration is the developmental direction of InSAR in the future.
