A novel analysis method of deformation accuracy for spaceborne PS-DInSAR
Spaceborne PS-DInSAR is an advanced remote sensing technology for achiving global surface deformation measurement, it has a series of advantages such as all time and weather, low cost, high deformation accuracy and so on. This paper focuses on the deformation accuracy of PS-DInSAR. Based on basic principle of spaceborne DInSAR, this paper introduces the principle of PS-DInSAR, and sets up the mathematical model of PS-DInSAR deformation accuracy, deduces the accuracy model of PS-DInSAR deformation detection by a novel method. Besides, PS-DInSAR deformation accuracy is analyzed by simulation. The research of this paper has guiding significance for the analysis of spaceborne PS-DInSAR overall performance.
