Rational Function Model for Conversion of InSAR Unwrapped Phases to Heights
Interferometric Synthetic Aperture Radar (InSAR) has become one of most potential technologies of earth observation. It has some prominent advantages, such as fast, high accuracy, all-daytime and all-weather, etc. In the processing of InSAR, the accuracy of derived height is highly related to the accuracy of estimated baseline parameters. Minor errors in baseline estimation can induce a major slope in derived DEMs (Digital Elevation Models). In order to get accurate heights from unwrapped interferometric phases, the rational function model for conversion of InSAR unwrapped phases to heights was proposed. It was used as a new model for conversion of unwrapped interferometric phases to heights. The interferometric data of S1R-C/X-SAR and of an airborne dual-antenna InSAR were employed to do experiments. And the unwrapped interferometric phases were converted accurately to heights, as showed that the rational function model is valid for unwrapped phases converting to heights.
