摘要

The dual-frequency SAR interferometry is an extension of the traditional SAR interferometry. Two interference phases with different ambiguity are used in two frequency bands to reduce the phase aliasing in steep regions, facilitate the phase unwrapping, reduce data noise and improve the accuracy of height estimation. In order to obtain high-precision interferometric elevation information in local areas flexible, SKL-SGIIT is developing the dual-frequency polarimetric advanced SAR system (Dupa-SAR) of unmanned aerial vehicle (UAV). In this paper, the parameters, and simulation results of InSAR performance of Dupa-SAR is presented.
