Abstract

Abstract

Estimation of topography for the generation of Digital Elevation Models (DEM) requires the absolute interferometric phase. However, the existing absolute phase determination methods are complicated for processing the Ultra-WideBand (UWB) Synthetic Aperture Radar Interferometry (InSAR) data. To resolve this problem, a new approach is proposed in this paper. First, to acquire the high accuracy image registration result, the registration offsets are obtained from the interpolation of the offsets of the control points. Then, based on the offsets, the interferometric phase is computed and divided into two partsthe Registration Phase (RP) and the MisRegistration Phase (MRP). The RP is derived from the registration offsets, and the MRP is dependent on the unknown misregistration. Theoretical derivations show that the MRPs are unambiguous in most high coherence areas, so MRP can be unwrapped efficiently, and its absolute phase can be obtained directly without using any auxiliary data. Finally, the absolute interferometric phase is obtained from adding the RP and the true MRP. Compared with the existing algorithms, the proposed approach has lower complexity. Experimental results on P-band UWB InSAR data prove its effectiveness.
