Theoretical Analysis of Building Height Estimation Using Space- Borne Sar-interferometry for Rapid Mapping Applications

چکیده
The great potential of space-borne SAR images for semior fully-automatic mapping of topographic features has been shown by many approaches. While most of them focus on 2D mapping of topographic features, some preliminary research on the complex task of automatic delineation of 3D information in urban environments has been initiated in recent years. In this paper, we analyze the capabilities of new space-borne interferometric SAR missions – in particular the German TanDEM-X mission – with respect to their potential of deriving building heights. To this end, we summarize the mathematical framework and carry out a thorough analytical accuracy analysis involving various sensor and scene parameters.

Comparison of Local and Non-Local Methods in Covariance Matrix Estimation by Using Multi-baseline SAR Interferometry and Height Extraction for Principal Components with Maximum Likelihood Approach
By today, the technology of synthetic aperture radar (SAR) interferometry (InSAR) has been largely exploited in digital elevation model (DEM) generation and deformation mapping. Conventional InSAR technique exploits two SAR images acquired from slightly different angles, in which the information of elevation and deformation can be captured through processing of the phase difference of the image...

This paper introduces a new and novel radar interferometry based on Doppler synthetic aperture radar (Doppler-SAR) paradigm. Conventional SAR interferometry relies on wideband transmitted waveforms to obtain high range resolution. Topography of a surface is directly related to the range difference between two antennas configured at different positions. Doppler-SAR is a novel imaging modality th...
