SummaryTraditional deformation model is empirical mathematical model, the physical significance is unclear, and the physical deformation process of road surface with time is not considered. The main objective of this proposal is to use TerraSAR Data to deduce high precision displacement observations on road surfaces and propose a new deformation model considering physical parameters.Concretely, with analysis of the rheological model, the rheological parameters will be analyzed, and the relational functional model between the LOS deformation and rheological parameters will be set up; A new efficient and accurate parameter estimation method will be studied, in the purpose of solving the complicated nonlinear parameter estimation problem; The significance of parameters in the new model will be tested meticulously, in order to optimize the rheological parameters; The sensitivity analysis will be carried out comprehensively, to show the error transformation discipline between the observation and parameters. All of the above will be served to inverse the deformation on road surface. In this project, we require some TerraSAR-X data covered highway area near Hunan and Guangdong province in China,which is convenient for carrying out ground truth observation.
