In this letter, the phase compensation method is proposed to remove the phase error in Pi-SAR-X2 POLSAR data. In August and October 2013, Pi-SAR-X2 observations were carried out. In a part of VH and VV observation data, the undesired phase pattern appeared. This phase error was caused by the mismatch between the flight navigation data and polarimetric raw data. The compensation method based on the reciprocity principle is considered. The experimental results show the usefulness of the proposed method and it is shown that the undesired phase pattern is clearly removed in the compensated data.
