【 摘 要 】

References(9)In this letter, the phase compensation method to remove an interfering phase in Pi-SAR-X2 POLSAR data is proposed. This phase is induced when a steep surface is observed by the H and V polarization antennas which are vertically placed. The proposed method removes the phase errors by using the elevation data which is acquired with the slave-V antenna displaced in the cross-track direction (for interferometric observation). The experimental results show the usefulness of the proposed method.
