| Popis: | Aiming at the problem of wrong selection and missed selection of interferometric image pairs by spatial-temporal small baseline combination method in time series SAR interferometry, this paper proposes an automatic method for selecting the optimum interferometric image pairs based on the coherence of interferograms. By quantitatively evaluating the coherence of point targets in a small feature region like urban area, this method can generate high-quality interferograms with high coherence from all possible interferometric combinations. |
