Improved determining weight method for GPS-DInSAR integration monitoring and simulation experiment analysis
Abstract：The analytical optimization algorithm which integrates GPS and DInSAR to monitor three-dimensional surface deformation was analyzed and its shortcomings in determination of weight were given.An improved determining weight method was presented,which used the high accurate GPS as constrain to evaluate DInSAR measurement accuracy and GPS interpolation accuracy,then weighed the DInSAR and GPS measurements.The simulation results show that the proposed method can correctly weight DInSAR measurement and GPS interpolation and is simple in realization.The analytical optimization algorithm using the improved determining weight method can offer the better results in the north,east and up direction.
