The nadir track of geosynchronous satellite can be circular with appropriate orbit parameters. Based on the characteristics of the interferometric phase of geosynchronous circular SAR (GEOCSAR), the method of three-dimensional (3D) surface displacement estimation is proposed. Correspondingly, the retrieval matrix is derived and then is optimized by choosing appropriate parameters. The simulation results validate the correctness of the analysis.
