| Abstract: | Quality-guided phase unwrapping algorithm is one of the most effective methods. In this category of algorithms, the pixels are unwrapped from the high quality points to the low quality ones. The success rate of phase unwrapping strongly depends on the quality map. We employ three quality maps (i.e., pseudo-correlation, phase derivative variance map and maximum phase gradient) as the guided maps and make some comparative analyses among them aiming to indicate which map performs best in general case. |
| Keywords: | InSAR InSAR phase unwrapping quality-guided phase unwrapping algorithm pseudo-correlation map simulation data |
