Abstract

Spotlight SAR interferometry is an attractive option for high resolution mapping and monitoring. In this paper, the signal spectral characteristics and the interfeometric properties of spaceborne spotlight SAR are analyzed completely, and the effect of the azimuth-variant Doppler to spotlight SAR interferometry is studied. Moreover, a new coregistration algorithm, which contains coarse coregistration, azimuth spectral filter, and accurate coregistration with adaptive subspace projection, is proposed for spotlight SAR interferometry. The algorithm is validated with real data experiment.
