Two SAR swaths over Tianjin, ALOS and TSX. Tianjin is affected by a strong non-linear motion. So, we can combine L and X band. L band covers a wider area, with long wavelength (~23 cm), longer revisit time (~46 days). X band can be focused on the most moving areas based on L band analysis. X and has shorter wavelength (~3cm) and covers a smaller area, but with higher revisit time (11 days).
